Abstract
A laser light source () and a heat-radiating plate () are provided on a pickup base (). The laser light source () irradiates a laser beam to an optical disk (). The heat-radiating plate () has at least one part exposed outside the pickup base (), having a predetermined distance between the heat-radiating plate () and the pickup base (), and radiates heat generated by the laser light source (). The plate () can radiate heat also from a surface opposing the pickup base () and can therefore have a high heat-radiating efficiency.
