ELECTRONIC CIRCUIT DEVICE

摘要

PROBLEM TO BE SOLVED: To improve reliability in an electronic circuit device by relaxing stress operating on a flexible wiring board around a connection section with a connection terminal at the side of a circuit board. SOLUTION: The electric circuit device 20 includes: the circuit board 22 with electronic components 21 packaged thereon; and the flexible wiring board 23 permitting electric connection between the circuit board 22 and external equipment. The circuit board 22 has a plurality of connection terminals 26 disposed side by side on a non-packaging surface. The flexible wiring board 23 includes: a plurality of connection terminals 236 disposed side by side on the surface so that they oppose the connection terminals 26 of the circuit board 22; and a plurality of free ends 23f that are formed such that each accommodates one of the connection terminals 236. Each free end 23f is not adhered to the circuit board 22, and the connection terminals 26 and the corresponding connection terminals 26 are electrically connected while facing one another.
