ツプ装置。 For receiving a light beam modulated on a signal surface of a signal recording medium and detecting a focusing deviation of the light beam on the signal surface and/or a tracking deviation of the light beam on a signal track on the signal surface. In an optical pickup device equipped with a photodetector, a part of a printed circuit board to which the photodetector is soldered is fixed to a base on which various optical elements are arranged, and the elasticity of the printed circuit board allows the printed circuit board to be soldered. A mounting portion of the substrate to which the photodetector is attached is made movable with respect to the base, and by displacing the mounting portion, photodetection is performed in the optical axis direction of the light beam received by the photodetector. An optical pickup device characterized by adjusting the position of the device.
