Abstract
A vehicle lamp includes a plurality of light emitting modules electrically connected together. Each of the light emitting modules includes a wiring board, a plurality of semiconductor light emitting devices arranged on one surface of the wiring board, a first wiring electrically connected to first conductive electrodes of the semiconductor light emitting devices and arranged on the one surface of the wiring board, and a second wiring electrically connected to second conductive electrodes of the semiconductor light emitting devices and extending to another surface of the wiring board through a via hole. The first wiring of at least one of the light emitting modules and the second wiring of the neighboring light source module overlap each other in a thickness direction of the light emitting modules, such that the light emitting modules are connected in series.
