Optical disc apparatus

An optical disc apparatus of the present invention is configured to include: a chassis which includes a supporting portion that supports an optical pickup, a pickup moving mechanism, and a disc motor, and coupling portions that are coupled to a tray at plural points, which is formed of a synthetic resin material, and in which the supporting portion and the coupling portions are integrated with each other; and a flexible flat cable which electrically couples between a first circuit substrate fixed to the bottom case side and a second circuit substrate fixed to the tray or the chassis side, and which is arranged between a bottom cover and a bottom case while its plane surface is folded in a state where the tray is inserted into an apparatus body.
