Light emission device

A light emission device comprising:

• a base part having an upper surface and a lower surface;
• one or more semiconductor laser devices disposed on the upper surface of the base part;
• a frame body having a flat region that is above the lower surface of the base part and outside a region in which the one or more semiconductor laser devices are disposed, the flat region extending in a lateral direction, and the frame body having a throughhole that extends from an upper surface to a lower surface of the flat region;
• an electrical conduction member disposed on a lower surface side of the flat region, the electrical conduction member including on an upper surface thereof a first conductive region and an insulative region, such that the first conductive region and the insulative region are located in a region defined by the throughhole of the frame body in a top plan view;
• and
• wiring having an end that is bonded to the first conductive region of the electrical conduction member to electrically connect the one or more semiconductor laser devices.
