PROBLEM TO BE SOLVED: To use a rigid substrate even in a thin type optical pickup device.SOLUTION: An optical pickup device has a bottom face and a side face surrounding the bottom face, and includes: a housing with an open upper face; a laser unit installed inside the housing and emitting laser light for performing recording and reading of information on an optical disk in a direction along the bottom face; an optical component installed inside the housing and disposed on the optical path of the laser light; and a rigid substrate installed in the housing so as to be overlapped on the laser unit from the upper face side and formed with a conducting path for transmitting a drive signal for driving the laser unit to the laser unit. The rigid substrate is installed inside the housing so that a surface against the bottom face approaches the bottom face more than the upper end part of the laser unit. |
