PROBLEM TO BE SOLVED: To provide a bulb for a vehicle preventing a counterpart electrode terminal from contacting a heat sink to avoid a short circuit. SOLUTION: The bulb for a vehicle is provided with a lens 2 distributing light emitted from an LED 1, a circuit body 6 with an insulation base board 5 on which there is formed an electric circuit part which is inserted into and electrically connected with a socket 4 having a counterpart electrode terminal 3, a heat sink 7 radiating heat emitted from the LED 1 and mounting the lens 2 on its tip side and fixing the circuit body 6 on a base end side, a fixing means preventing a contact between the counterpart electrode terminal 3 and the heat sink 7 and fixing the circuit body 6 with the heat sink 7. The fixing means is composed of a first insulation fixing member 16 and a second insulation member 17 of an identical shape made of an insulation material and the circuit body 6 is pinched by these fixing members from either side to be jointly fixed.
