Patent ID: 7934856

Claim:
An illumination device comprising: a base having heat radiation properties and including a projection which projects from a surface, the projection including a distal end face and formed integrally with the base; a light reflecting insulator laminated on an area of the surface of the base excluding the projection, the distal end face of the projection projecting beyond the insulator to a side opposite to the base; conductors formed on the insulator, each of the conductors including an end edge which is apart from the projection, the insulator being exposed from between the end edge of each of the conductors and the projection; a light reflective layer made of metal and laminated on each of the distal end face of the projection and the conductors, the light reflective layer being formed on the distal end face and the conductors by electroless plating, the light reflective layer having a thickness of 0.003 mm to 0.005 mm and a light reflectance of 90% or more; a semiconductor light-emitting element mounted on the light reflective layer covering the distal end face of the projection, the semiconductor light-emitting element including a light-transmissive substrate, a light-emitting layer provided on the light-transmissive substrate, and electrodes provided on the light-emitting layer, the light-transmissive substrate being bonded onto the light reflective layer by a light-transmissive bonding material, the light-emitting layer projecting beyond the insulator and the conductors to the side opposite to the base; connection members which electrically connect the conductors and the electrodes of the semiconductor light-emitting element; and a light-transmissive sealing member which covers the insulator, the projection, the semiconductor light-emitting element and the connection members.
