Abstract
A light emitting device capable of efficiently dissipating heat outward, and a method producing it are provided. The light emitting device includes an insulating board, a metal member, a light emitting element, a conductive member and a transparent member. The insulating board has a through hole. The metal member is inserted into the through hole. The light emitting element is mounted on the top surface of the metal member. The conductive member is formed on the insulating board and is electrically connected to the light emitting element. The transparent member covers the light emitting element and the top surface of the insulating board. The conductive member is continuously formed from the top surface to the bottom surface of the insulating board. The bottom surface of the metal member is substantially coplanar with the bottom surface of the conductive member on the bottom surface side of the insulating board.
