A circuit module 14 includes: a lighting control circuit 22 that controls lighting of a semiconductor light emitting element; a first heat radiating member 24 on which the lighting control circuit 22 is mounted; a second heat radiating member 26 that is separated from the first heat radiating member 24 and has a surface 40a on which the semiconductor light emitting element is mounted; and a connecting mechanism 28 having both a housing 30 that connects the first heat radiating member 24 and the second heat radiating member 26 together and a conductive portion 32 that transmits a signal from the lighting control circuit 22 to the semiconductor light emitting element. The housing 30 is formed of a material having a coefficient of thermal conductivity lower than those of the first heat radiating member 24 and the second heat radiating member 26.
