To provide a light-emitting module capable of preventing occurrence of short-circuiting.
The light-emitting module includes: a ceramic substrate 2 having one side surface out of outer peripheral surfaces formed in an approximately rectangular shape as an abutting surface 2c which is abutted to positioning surfaces 20a, 20a of a radiator 16, and having one side surface out of surfaces in a thickness direction formed as an element arranging surface 2a where light-emitting elements 3 are arranged; given conductive patterns 5, 5 formed on the ceramic substrate; a light-emitting section 3A having the light-emitting element; and a pair of positive and negative planar electrodes 6, 6 formed on the ceramic substrate and connected with the semiconductor light-emitting element through the conductive patterns. At least parts of the pair of planar electrodes are to be exposed zones 6a, 6a exposed to the element arranging surface of the ceramic substrate, respective exposed zones of the pair of planar electrodes are located at a section excluding both ends in one direction of the ceramic substrate, and non-exposed zones are located on both ends in the one direction of the ceramic substrate.
