Abstract:
1. A light-emitting device comprising: a mount member mounting a semiconductor light-emitting element, wherein the mount member is mounted on a circuit board, wherein at least part of the mount member comprises a multilayer board, and a first conductive pattern formed on a surface layer of the multilayer board and a semiconductor light-emitting element are electrically connected, wherein on the multilayer board, a second conductive pattern formed on a layer positioned closer to the circuit board than the first conductive pattern is electrically connected to a conductor part of the circuit board and power is fed from the conductor part to the semiconductor light-emitting element via the second conductive pattern and the first conductive pattern, wherein said mount member includes a step part exposing part of the second conductive pattern and wherein electric connection between the semiconductor light-emitting element and the first conductive pattern is made by face-down bonding, and wherein a conductive wire is used for electric connection between the second conductive pattern and the conductor part of the circuit board and the conductive wire does not protrude toward the element from a surface of the mount member mounting the semiconductor light-emitting element relative to the circuit board.
