An optical pick-up apparatus that irradiates a disk with laser light emitted from a laser light source and uses a photodetector to receive the laser light reflected by the disk to thereby perform recording/reproduction onto/from the disk, comprises: a laser diode driver that drives the laser light source; an upper cover that serves as a heat radiation means for radiating heat generated by the laser diode driver; and an optical base that serves as a heat radiation means for radiating heat generated by the laser light source and photodetector.
