Provided is a socket capable of making the inclination of a plunger smaller than the conventional art. A second plunger (12) includes a base-end columnar portion (12a) and a pin-shaped portion (12b). An outer peripheral surface of the pin-shaped portion (12b) includes an inclined portion (12c) that becomes smaller in diameter toward a leading end of the pin-shaped portion (12b). The inclined portion (12c) is a tapered surface that is inclined so as to be symmetrical about a central axis of the pin-shaped portion (12b). The amount by which the second plunger (12) is able to protrude from an insulating support (2) is regulated by the inclined portion (12c) contacting (engaging with) a small-diameter portion (2c) of the insulating support (2). When the second plunger (12) is inclined with respect to a stroke direction, an engagement portion between the inclined portion (12c) of the second plunger (12) and the small-diameter portion (2c) of the insulating support (2) acts as a point of support. |
