Light source module and lighting device for a vehicle, to reduce the number of components in a light source module. The light source module is provided with a ceramic circuit board 2 on which conductive patterns 2a, 2a are formed, a semiconductor light-emitting element 3 which is arranged on the ceramic circuit board and connected to the conductive patterns, and a power feeding attachment 5 whichis connected to the ceramic circuit board on which the semiconductor light-emitting element is arranged. The power feeding attachment is provided with power feeding parts 9, 9 connected to the external power supply, a plate-like part 7b which adjoins the position opposed to the outer periphery of the ceramic circuit board and is formed of a resin material, power feeding terminals 10, 10 which areformed in plate shape and protrude to the ceramic circuit board side from the plate-like part and of which tip part is superposed from the thickness direction and connected to a part of the conductive pattern. The power feeding terminals of the power feeding attachment and the conductive pattern of the ceramic circuit board are fixed and connected by welding.
