In the optical head according to the present invention, when a holder, which is provided with an optical element fixedly disposed thereon, is fixed to a housing member, the holder is housed in a guide hole of the housing member and then a screw is screwed into a tapped hole formed in the housing member not so as to reach the guide hole to press a bottom portion of the tapped hole against the holder. Accordingly, with the optical head according to the present invention, a torque of rotation generated when the screw is rotated is absorbed in the bot- tom portion of the tapped hole, so that the holder is not moved when the screw is screwed into the tapped hole, where- by the optical element fixedly disposed on the holder can be easily positioned at an appointed position.
