In a disc driving apparatus, wherein a laser diode 27 and a laser driver circuit board 29 are mounted on a pickup housing 24, being connected with thermally and disposed adjacent with each other, and a heat separation member 25 is provided between the laser diode 27 and the laser driver circuit board 29 for thermal separation therebetween, thereby reducing the thermal interference between the heat-generating elements disposed to be adjacent in the optical pickup, so as to protect the heat-generating elements from being deteriorated on lifetime thereof, as well as, improve the reliability thereof.
