An optical pickup is provided which is capable of minimizing an astigmatism thereof with a simple configuration. The optical pickup includes a collimate lens for transferring optical beams outputted from a laser diode to parallel light, and an objective lens for collecting the optical beams transferred to parallel light with the collimate lens and applying the optical beams to an optical disk, wherein mounting angles of the collimate lens and the objective lens are adjusted so that astigmatisms of the collimate lens and the objective lens may be offset by each other. Thus the astigmatism of the optical pickup can be minimized with a simple configuration without need for separately providing an element for correcting aberration.
