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