Abstract:
1. An illumination device comprising: a base hoard having heat radiation properties, the base board including a surface and a plurality of projection portions, each projection portion having a distal end face and an outer peripheral surface, the distal end face being covered with a light reflective layer, the outer peripheral surface being flared from the distal end face towards the surface of the base board; an insulator formed on the surface of the base board, the insulator having a plurality of through holes through which the projection portions penetrate; a conductor formed on the insulator; a plurality of semiconductor light-emitting elements which are bonded by light-transmissive bonding materials to the light reflective layers formed on the distal end faces of the projection portions of the base board; connection members which electrically connect the conductor and the semiconductor light-emitting elements; and a light-transmissive sealing member which covers the insulator, the projection portions, the semiconductor light-emitting elements and the connection members.
