THREE-DIMENSIONAL CIRCUIT BOARD AND FINGERPRINT SENSOR DEVICE

摘要

A three-dimensional circuit board and a fingerprint sensor device are provided to position a detecting surface of a fingerprint sensing device accurately relative to a window hole provided at housing for an electronic device. A fingerprint sensing device(101) converts a fingerprint image obtained from its flat detecting surface(104) into an electric signal. The detecting surface is exposed to an outside of housing(200) of an electronic device through a window hole(201) provided at the housing, and is mounted on a printed wiring board(120) accommodated in the housing. A synthetic resin molded component(C2) includes a mounting portion(1) in which a concave portion for accommodating the fingerprint sensing device, and at least one leg portion(2) having one end portion connected to the mounting portion and the other end portion mounted on the printed wiring board. A conductive body is provided on the synthetic resin molded component, and electrically connects an output terminal of the fingerprint sensing device mounted on the mounting portion with a conductive pattern formed on the printed wiring board.
