ABSTRACT:
A laser light source (61) and a heat-radiating plate (71) are provided on a pickup base (51). The laser light source (61) irradiates a laser beam to an optical disk (41). The heat-radiating plate (71) has at least one part exposed outside the pickup base (51), having a predetermined distance between the heat-radiating plate (71) and the pickup base (51), and radiates heat generated by the laser light source (61). The plate (71) can radiate heat also from a surface opposing the pickup base (51) and can therefore have a high heat-radiating efficiency.
