Claim Text:
1. A light-emitting module comprising: a semiconductor light-emitting device provided with at least a semiconductor light-emitting element and a phosphor; and a circuit board for supporting the semiconductor light-emitting device mounted thereon, wherein, on the circuit board, at least a semiconductor light-emitting device including a plurality of semiconductor light-emitting elements each having a different path of a drive current to be supplied or a plurality of semiconductor light-emitting devices each having a different path of a drive current to be supplied to each semiconductor light-emitting element is mounted, the circuit board is provided with a base material portion formed using a heat-conducting material; and a power supply conductor layer for supplying the drive currents for semiconductor light-emitting elements to the semiconductor light-emitting devices, the power supply conductor layer is formed planarly using the heat-conducting material so as to cover a planar surface of the base material portion, and the planar region of the power supply conductor layer is planarly divided by an insulator for each of the drive current paths.
