This is also the same as the conventional example (see FIG. 3). For example, the replacement of the bulb 12 does not cause a sense of incongruity with the conventional example.

Here, in the present invention, the socket 2 is provided with a contact piece 2a, which is provided, for example, in a socket hole provided on a printed circuit board and having a terminal portion made of copper foil at an appropriate position. Any structure may be used as long as it has a configuration similar to a wedge base socket with a contact piece currently used for mounting a light bulb.

In the present invention, a clamper 3 is provided on the back surface of the housing 11, and the clamper 3 includes, for example, a pair of opposed spring portions 3a and a pair of spring portions 3a as shown in FIG. And the metal wire holding portion 3b provided in the housing 11, and are formed integrally when the housing 11 is formed.

The clamper 3 is provided for holding a metal wire 4 at a predetermined position, which will be described later, and in order to meet this purpose, the metal wire holding portion 3b uses a wire of the metal wire 4 to be used.
