Abstract: A magnetic sensor of the present invention includes a Hall-effect sensor configured to detect magnetism and an IC being configured to drive the Hall-effect sensor and perform signal processing therefor and having two or more metal interconnection layers. The Hall-effect sensor and the IC are electrically connected to each other via wire interconnections and sealed in one package. Metal interconnections on the IC to input output voltage of the Hall-effect sensor to a signal processing unit of the IC have a grade-separation junction portion in order to suppress an induced electromotive force which a change in the magnetic flux density externally applied generates at output terminals of the Hall-effect sensor, the wire interconnections connected to output electrode pads of the Hall-effect sensor, and the metal interconnections to input the output voltage of the Hall-effect sensor to the signal processing unit of the IC.

Abstract: An infrared-sensor filter member includes an optical filter disposed in an opening portion of a second member and a first member. The infrared-sensor filter member includes a recess portion formed from a light-incident surface of the optical filter and the first member. At least a part of a bottom surface of the recess portion is formed by the light-incident surface and side walls of the recess portion, which are formed by the first member.
