Abstract
A wiring board for a light-emitting element includes a ceramic insulating substrate, and a conductor layer formed on the surface or in the inside of the insulating substrate, the conductor layer having a mounting region mounting a light-emitting element on one surface of the insulating substrate. The insulating substrate includes a heat-conducting pole-like conductor having a thermal conductivity higher than that of the insulating substrate. The heat-conducting pole-like conductor extends through the insulating substrate in the direction of thickness thereof from the light-emitting element mounting region of the insulating substrate, and is formed by the co-firing with the insulating substrate.
