WIRING BOARD, ELECTRONIC DEVICE PACKAGE, AND METHODS OF PRODUCTION OF THE SAME

A wiring board which uses both conductor patterns and reflection members provided at gaps therebetween to suppress unevenness in the reflection rate so as to raise the overall reflection rate and provide a reflection function on the surface of the wiring board at the side where an electronic device...

Zusammenfassung:	A wiring board which uses both conductor patterns and reflection members provided at gaps therebetween to suppress unevenness in the reflection rate so as to raise the overall reflection rate and provide a reflection function on the surface of the wiring board at the side where an electronic device is mounted; facilitates shaping of the reflection members, controlling of the thickness of the reflection members, and controlling of the surface shape of the reflection members so as to stabilize the reflection rate; and secures close contact between the reflection members and sealing members so as to improve reliability. The wiring board comprises a plurality of wiring layers provided with conductor patterns disposed on base members, and base members which electrically insulate the plurality of wiring layers. At the outermost wiring layer among the plurality of wiring layers, reflection members are formed on the portions of the base member where there are no conductor patterns, the surface of these reflection members and the surface of the conductor patterns are made level and the surface of the conductor patterns are exposed from the reflection members.
