    Abstract: PROBLEM TO BE SOLVED: To provide a junction structure of a conductor which can reduce connection failure even if an inner conductor and a surface conductor are different in composition. SOLUTION: A tip part 2a of an inner conductor (Ag) 2 is joined to a surface conductor (Ag-Pd) 31. That is, the tip part 2a of the inner conductor 2 (pattern width of 250 μm) is formed to overlap with a surface conductor 31 by 50 μm or more, for example, from a long side of a pattern width of 600 μm of the surface conductor 31, and the overlapping part is made a junction part 35. Especially, since the inner conductor 2 does not comprise Pd, difference of Pd concentration of the inner conductor 2 and the surface conductor 31 in the junction part 35 is in the range of 15 wt.% or less (5 wt.%, for example).

    Abstract: PROBLEM TO BE SOLVED: To provide a ceramic circuit board which has a conductor film and a minute-area resistor film of precise dimensions formed on a ceramic board and also provide a manufacturing method thereof. SOLUTION: A ceramic circuit board is manufactured by screen-printing conductor paste and resistor paste on a ceramic green sheet 1a and baking them. At that time, a pair of dams 3a made of insulator paste are formed at an interval which is equal to the width of a resistor film to be formed from resistor paste, and then resistor paste is printed between the dams 3a and is baked. The resistor paste is prevented from bleeding in the width direction by a pair of the dams 3a and thereby the resistor film 4 of high dimensional accuracy can be formed. Especially, the thickness of the dams 3a are made smaller than that of the resistor film 4a, but not excessively smaller in the balance between the resistor film 4a and the dams 3a. Therefore, the resistor film 4 of high dimensional accuracy can be efficiently formed with good reproducibility.
