Patent ID: 7440386

Claim:
An optical device, comprising: a bendable flexible substrate and an optical element on a metallic frame body; and an optically transparent member above the optical element via a frame, the frame body having a flat central frame plate and a pair of side frame plates bent from both ends of the central frame plate, the flexible substrate having a central substrate covering the central frame plate and bent substrates bent from the central substrate so as to cover the side frame plates, the flexible substrate being fixed on the frame body via the frame, the optical element being mounted in contact with a surface of the central frame plate of the frame body, the flexible substrate having internal wiring terminal groups each being composed of a plurality of internal wiring terminals connected to the optical element, external wiring terminal groups each being composed of a plurality of external wiring terminals used for connection to external equipment, and wiring patterns for connecting the internal wiring terminals and the external wiring terminals, the internal wiring terminals being disposed on the central substrate of the flexible substrate and arranged in a width direction which is parallel to the central frame plate of the frame body and is an opposing direction of the pair of side frame plates, and the external wiring terminals being arranged on the bent substrates of the flexible substrate and arranged in a length direction which is parallel to the central frame plate of the frame body and orthogonal to the width direction.
