Abstract: PROBLEM TO BE SOLVED: To provide an electronic tube which has good airtightness and is suitable for mass production. SOLUTION: In this electronic tube, indium 23 is arranged sticked to an inner circumferential surface of a metallic support body 24 for sealing, disposed between a side tube 10 and a input surface plate 21. When the input surface plate 21 is pressed against the side tube 10, the indium 23 is crushed by a metallic sealing crushing surface 70 provided on an end face of the side tube 10. At this time, because this metallic sealing crushing surface 70 has a shape which is cut down from inside to outside, the indium 23 is deformed, while escaping outside towards the metallic support body 24 for sealing. Accordingly, the indium 23 is steadily attached under pressure to the metallic sealing crushing surface 70, whereby sealing between the input surface plate 21, and the side tube 10 can be steadily conducted by the indium 23.

Abstract: PROBLEM TO BE SOLVED: To provide an electron tube having good airtightness and suitable for mass production. SOLUTION: In this electron tube 1, indium 23 stuck to the peripheral wall of the inner wall of a metal support 24 for sealing is interposed between a container 10 and an input face plate 21. The input face plate 21 is pressed against a container 21. Where, a first and a second protrusion parts 71, 72 formed at the end of the container 10 deform the indium 23. Indium 23 pushed out by deformation is pushed into a metal-housing recessed part 73 for sealing provided between the first protrusion part 71 and the second protrusion part 72. Therefore, deformation afforded to the indium 23 surely press-fits indium 23 to the wall faces of the first and the second protrusion part 71, 72 and simultaneously, securely press-fits indium 23 to the wall face of the metal-housing recessed part 73 for sealing as well. The indium 23 positively assures sealing between the input face plate 21 and the container 10.

Abstract: PROBLEM TO BE SOLVED: To provide a photomultiplier tube of a micro structure realizing stable detection accuracy.
SOLUTION: The photomultiplier tube is provided with an envelope with the inside maintained in vacuum, in which, a photoelectric face (22), an electron multiplier (31), and an anode (32) are arranged. Especially, one or more control electrodes (320) arranged in an inside space of the envelope surrounding the electron multiplier (31) and the anode (32) are electrically connected through one or more connecting parts extended from electron emission ends of the electron multiplier (31). In this structure, voltage impressed between an electron incident end and an electron emission end of the electron multiplier (31) is impressed between the electron incident end and the control electrode, so that a potential gradient gradually increasing from a photoelectric face (22) side toward an anode (32) side is formed at the electron multiplier (31), and at the same time, a substantial potential difference is given between the electron emission end of the electron multiplier and the anode (32) to have stable detection accuracy obtained.
