ABSTRACT:
The present invention provides a light emitting device which comprises a light emitting element, a mounting board on which the light emitting element is mounted, a metal-made reflector surrounding the side surfaces of the light emitting element on the mounting board, a conductor for electrically connecting the light emitting element with the mounting board, and a sealing resin fitted within the reflector to cover and seal the light emitting element and the conductor. The mounting board includes a metal-made base board, and an insulating board laminated on the base board and formed with a window hole extending therethrough which is larger than the outer periphery of the light emitting element. A mount for carrying the light emitting element thereon is disposed on the base board within the window hole with a clearance defined from side surfaces of the window hole. The conductor straddles the clearance, and electrically connects the wiring pattern formed on the insulating board with the light emitting element and the mount. Then, part of the clearance associated with the area that projects from the conductor to the mounting board is narrower than the rest of the clearance.
