In an optical disc device, the device effectively reduces noise generated during the time of optical disc revolution and at the same time prevents a tray and an optical disc placed on the tray from coming into contact with each other or a circuit board mounted on the tray from undergoing electrostatic destruction. A circuit board for controlling a spindle motor and a pickup is mounted on a tray for placing an optical disc on the reverse side of the rear area. There are formed through-holes crookedly piercing through the tray in the thickness direction in the rear area of the tray. The through-holes are so constructed that their openings on tray's reverse side are invisible from their openings on tray's face side.
