There is provided an optical pickup apparatus which is small in size and excellent in releasing action of heat generated inside the apparatus. An optical pickup apparatus includes semiconductor lasers as light sources for emitting light, a laser driver for controlling light emitting operations of the semiconductor lasers, a first housing in which the laser driver is housed, and a second housing in which the semiconductor lasers are housed. The first housing 31 and the second housing are separately formed and connected to each other so as to have a void portion therebetween, which penetrates the first housing and the second housing in thickness directions thereof. The laser driver and the semiconductor lasers are disposed so as to be adjacent to each other via the void portion, and housed in the housing.
