Electric power feed device and vehicle lamp

摘要

An electric power feed device (10) is adapted to feed electric power from a power supply to a vehicle lamp which uses at least one semiconductor light emitting device (50) as a light source. The electric power feed device (10) has a bus bar (20) and an interposing unit (100) which is attachable to the bus bar (20). The bus bar (20) has a positive side connecting portion (21) adapted to be electrically coupled to a positive terminal of the power supply, and a negative side connecting portion (22) adapted to be electrically coupled to a negative terminal of the power supply to electrically couple the at least one semiconductor light emitting device (50) to the positive and negative terminals of the power supply. The interposing unit (100) is adapted to interpose and electrically couple, when attached to the bus bar (20), at least one electronic component (200) between the positive side connecting portion (21) and the negative side connecting portion (22) of the bus bar (20).
