Patent ID: 7257140

Claim:
A semiconductor laser device, comprising: a plurality of layers including a first conductive type semiconductor layer, an active layer, and a second conductive type semiconductor layer; a first electrode connected to said first conductive type semiconductor layer and a second electrode connected to said second conductive type semiconductor layer; wherein said second electrode comprises an ohmic electrode and a pad electrode, said ohmic electrode is ohmically connected to a portion of said second conductive type semiconductor layer in an ohmically connected region, and said pad electrode has a region for wire bonding; said first electrode is disposed on a common side of said first conductive type semiconductor layer as said second electrode, and said first electrode and said pad electrode are disposed in a common direction with respect to the ohmically connected region; and said second conductive type semiconductor layer has a predetermined width, wherein said second electrode comprising said ohmic electrode extends in a stripe shape, and said pad electrode is electrically connected to said ohmic electrode and projects in at least a first direction that is different from a second direction in which said ohmic electrode extends, wherein a projecting portion of said second conductive semiconductor layer projects in the first direction and said second electrode is disposed on top of said second conductive type semiconductor layer including the projecting portion.
