Abstract:
1. A light emitting module used in a lighting device for a vehicle and fixed to a radiating member in an abutting and positioning state to a positioning surface formed on the radiating member, the light emitting module comprising: a ceramic board formed in an almost rectangular shape and having one side surface in an outer peripheral surface formed as an abutting surface, which is caused to abut on the positioning surface of the radiating member, one surface in a vertical direction formed as a device disposing surface, and another surface in the vertical direction formed as a radiating surface, which is provided in face contact with the radiating member to radiate heat; a predetermined conductive pattern formed on the ceramic board; a light emitting portion, having a semiconductor light emitting device, disposed on the device disposing surface of the ceramic board and connected to the conductive pattern; and a pair of planar electrode portions formed on the ceramic board and connected to the semiconductor light emitting device through the conductive pattern, wherein at least a part of the pair of planar electrode portions are set to be exposure regions, which are exposed to the device disposing surface of the ceramic board, and the exposure regions of the pair of planar electrode portions are positioned in portions other than a portion linked to the abutting surface in an outer peripheral portion of the device disposing surface.
