1. A contact pin configured to electrically connect a first electric component with a second electric component, the contact pin comprising:
a pin body including an inner pin element and an outer pin element that are disposed at one end side and an other end side in an axial direction and telescopically combined such that, when the pin body is retracted, the inner pin element moves in a retracting direction of the axial direction toward the other end side to decrease a length of protrusion of the inner pin element from the outer pin element, and, when the pin body is extended, the inner pin element moves in an extending direction of the axial direction toward the one end side to increase the length;
an elastic member including a contractible spring configured such that, when the pin body is retracted, the spring contracts to urge the inner pin element and the outer pin element to extend the pin body; and
a pressing portion that is provided in the outer pin element, that includes a contacting portion configured to contact the inner pin element when the pin body is retracted, and that is configured to apply a force via the contacting portion to the inner pin element moving in the retracting direction, the force containing a component in a direction orthogonal to the axial direction, wherein
the contacting portion of the pressing portion is disposed at a position which is spaced apart in the retracting direction from a forward end portion of the inner pin element in the retracting direction when the pin body is extended and the length is maximized.
