PROBLEM TO BE SOLVED: To prevent deterioration in recording quality caused by an excessive increase in temperature of an objective lens-driving mechanism mounted on an optical pickup in an optical disk apparatus. SOLUTION: The optical disk apparatus includes: a mechanical chassis on which a disk rotation mechanism, an optical pickup, and a transfer mechanism are mounted; a decorative plate that is a plate-shaped member located between the disk and the optical pickup and fixed on the mechanism chassis; a disk tray for loading and removing the disk; a circuit board for operation control; and an apparatus housing containing the components. A recess is formed in an indented shape in a portion of the mechanical chassis facing an outer peripheral region of the disk recording surface. An incline is formed in a position close to an opening of the disk tray for mounting the mechanical chassis and opposite the outer peripheral region of the disk recording surface, and slopes gently down to the recess.
