PROBLEM TO BE SOLVED: To realize an optical pickup in which heat generated by a laser diode can be radiated surely. SOLUTION: This optical pickup is provided with a laser diode emitting a light beam, a heat radiation plate to which the laser diode is attached, a flexible substrate provided with at least one side of a drive signal to the laser diode and a wiring pattern for output signal from an optical detecting means, an optical system irradiating an optical disk with the light beam and guiding reflected light beam in which the light beam is reflected by the optical disk to the optical detecting means, and a flexible heat transfer member in which one end is connected to the heat radiation plate in a heat state and the other end is connected to the prescribed heat radiator in a heat state and which has heat conductivity and flexibility. Thereby, the heat generated by the laser diode can be transferred to the heat radiator surely and heat radiation can be performed. COPYRIGHT: (C)2005,JPO&NCIPI
