PROBLEM TO BE SOLVED: To assemble an LED so as to confirm continuity in a form of an incorporated type of the resistance, making a car plug have a form for reducing cost by reducing the number of outer electrode terminals without lengthening the axial length of the body of the car plug. SOLUTION: In the body 2 of the car plug, an outer electrode terminal 5 is assembled to a portion close to one side in a radial direction of the inner cavity. The projecting part 50 is projected from an opening 20 opened on the side close to the one side on a peripheral wall of the body 2 and the other side of the radial direction of the inner cavity of the body 2 is formed as an empty chamber w. On an opposite side of the projecting part 50 of the outer electrode terminal 5 on an outer peripheral surface of the body 2, a pair of projection parts 6 and 6 projecting from the outer peripheral surface are mounted by being arranged in parallel at an interval in the peripheral direction. The LED 7 is assembled to a proper portion at a portion close to a rear end side of the outer peripheral surface of the body 2. The resistance R provided on a circuit 7a of the LED 7 is assembled by being disposed within the empty chamber w. The circuit 7a is connected and conducted with the inner electrode terminal 3 and the outer electrode terminal 5.
