1. A lighting fixture for a vehicle comprising:
a light source;
a heat dissipating member which dissipates heat from the light source, the light source being placed on an installation surface of the heat dissipating member; and
a socket including an attachment surface on which the heat dissipating member is attached; wherein
the heat dissipating member includes a heat dissipating surface which is on a side opposite to the installation surface and faces the attachment surface of the socket when the heat dissipating member is attached to the socket, the heat dissipating surface including a first area in which a heat dissipating fin part protrudes from the heat dissipating surface, and a a second area provided lower than the heat dissipating fin part, in which a heat dissipating-side positioning part is provided at a predetermined position, and
the attachment surface including a fin groove part into which the heat dissipating fin part fits so that the heat dissipating fin part is located in the socket when the heat dissipating member is attached to the socket, and a socket-side positioning part provided at a position corresponding to the predetermined position of the heat dissipating-side positioning part to determine a relative position of the heat dissipating member to the socket.
