An optical element mounted on a wiring board is sealed by a sealing resin except an optical function region. Wires connecting the wiring board with the optical element are also sealed by the sealing resin. The optical function region is exposed as a bottom surface of a recess whose side surface is formed by the sealing resin. A boundary portion between the side surface of the recess and a top surface portion and a boundary portion between the side surface and bottom surface of the recess have a rounded shape.

A vehicular headlamp employing a semiconductor light-emitting device having a plurality of light-emitting elements such as LEDs and for which light distribution design is made easy. Separate ones of the light-emitting elements within the light-emitting device are employed for forming high and low headlamp beams. The light-emitting device also includes a reflector and a lens. The beams are switched by selectively activating predetermined ones of the light-emitting elements.

An optical device includes a copper plate, light receiving elements mounted on the copper plate, a light emitting element mounted on the light receiving elements, a flexible substrate bent to cover portions of upper and side surfaces of the copper plate, and a positioning frame of metal for fixing the flexible substrate and the copper plate to each other. Since the positioning frame secures the flexible substrate and the copper plate against movement, a thin optical device can be attained without employing a resin-molded construction.

A headlamp for a vehicle including a light-emitting device 14 that faces downward and is placed on an optical axis Ax, a reflector 16 which covers the device from the lower side, a mirror member 18 which reflects part of reflected light from a reflector 16 downward is disposed between the reflector 16 and a projection lens 12. The mirror member 18 has a downward reflecting surface 18a which extends rearward in parallel with the optical axis Ax from the vicinity of the rear focal point F in proximity to a portion above the optical axis Ax. In reflected light from the reflector 16, light which passes through the back focal plane of the projection lens 12 at a position which is above the optical axis Ax passes through a position which is close to the optical axis Ax.

An optical pick-up apparatus includes: a semiconductor laser light source that generates an optical beam; a diffraction grating that divides the optical beam into a main beam and side beams; an optical element that guides the main beam and the side beams that are generated by the diffraction grating onto an optical information medium; and a photodetector that detects a signal from reflected light reflected from the optical information medium. The semiconductor laser light source is configured with a 2-wavelength semiconductor laser device in which a semiconductor laser chip that generates an optical beam having a wavelength of λ1 and a semiconductor laser chip that generates an optical beam having a wavelength of λ2 are integrated into one chip or are arranged in proximity to each other. The diffraction grating has one grating period Λ by which each of the optical beams having the wavelength λ1 and the optical beam having the wavelength λ2, which are generated by the 2-wavelength semiconductor laser device, is divided into a main beam and side beams. The apparatus is applicable to two kinds of optical information media having different track pitches.
