PROBLEM TO BE SOLVED: To facilitate mounting in a base board and ensure electric connection, by providing a terminal metal fitting fixing one end side with the other end side as a free end to be made extensible/contractible in a holder axial direction. SOLUTION: A periphery of a holder 2 is mounted to be placed in a notch part 51 of a base board 5, a pair of terminal metal fittings 3, provided in an opposed surface of the outside surface, receive as a power receiving terminal a feed of power from a wiring conductor of the base board 5, a lamp 4 emits light through a lead wire 42 connected to the terminal metal fitting 3. In the case of insertion mounting this lamp device 1 in the base board 5, one end side 32 of the terminal metal fitting 3 is fixed, when a protruded surface part 31 of the terminal metal fitting 3 is brought into contact with the wiring conductor along a side surface in the notch part 51 of the base board, by the pressing force, only a free end in the other end side 33 is extended in the terminal metal fitting 3. Accordingly, a contact location of a terminal side 3 and the wiring conductor is always fixed, a contact condition with a mate base board is stabilized, also elasticity is given to the terminal metal fitting 3, so as to ensure electric connection to the wiring conductor. |
