In an optical pickup device for use in recording and reproducing on an optical recording medium, such as a CD or DVD, banks are formed on both sides of an adhesive agent application position for adhering an optical device, such as a photodetector or a laser diode, in an optical pickup case. At this time, a bank on the side of an optical path is formed higher than a height of an outer bank, and an adhesive agent is poured between the banks, to adhere the optical pickup case and the optical device.
