An optical pickup device is provided to enhance accuracy in correction by fixing a lens for the aberration correction of the optical pickup device to prevent the lens from being moved in a direction for which a user does not wish from a holder. A correction lens unit(230) includes a correction lens(230), a lens unit(220), and a holder(210). The correction lens(230) performs the focusing of one of one or more light sources. The lens unit(220), integratedly fabricated with the correction lens(230), fixes the correction lens(230). A groove of a certain shape is formed at one side of the lens unit(220). The holder(210) has a combination structure which is identical to the lens unit(220). A projection contacted with the groove is formed in a position of the holder(210) corresponding to the groove formed in the lens unit(220).
