1. A flexible circuit board mounted on an electronic circuit device, comprising:
- a plurality of mounting portions which are mounted with electronic circuits;
a connector portion that performs signal transmission between the electronic circuits mounted on each of the mounting portions and the electronic circuit device;
coupling portions that couple the mounting portions to the connector portion in different directions,wherein one of the mounting portions is coupled to a coupling portion including a predetermined part, and the predetermined part is provided with a notch or notches to move said one of the mounting portions in a parallel direction with respect to the other mounting portions in a state that said one of the mounting portions is bent around the predetermined part,wherein the coupling portion which includes the predetermined part has a longitudinal dimension longer than the longitudinal dimension of the connector portion such that when the connector portion is bent at the notch or notches of the predetermined part to a position where the longitudinal dimensions are about parallel, the connector portion does not overlap the mounting portion coupled to the coupling portion which includes the predetermined part, andwherein the flexible circuit board is mounted on the electronic circuit device in a state of being bent at the predetermined part.
