To provide an optical pickup device and optical disk device capable of
realizing at least one of thickness reduction, size reduction and
suppression against characteristic deterioration even where coping with
various wavelengths of laser including a blue laser. An optical pickup
device comprising light sources for respectively emitting a plurality of
different wavelengths of light, unit structured for causing at least a
part of the light emitted from the light sources to pass a same optical
path; and focusing unit for focusing the light. The focusing unit
includes at least first and second focusing parts, the first focusing
part being to focus mainly a wavelength of light different from a
wavelength of light to be mainly focused by the second focusing part.
