A pin contact of a connector includes a parallel portion which touches a contact portion of a contact spring portion of a socket contact when the pin contact is fitted into the socket contact, and an inclined portion to be inserted into the contact spring portion while forcibly opening the contact spring portion at the time of insertion. The inclined portion has a shape which is a combination of a curve portion and a linear portion, the curve portion being moderate in inclination in the area of a boundary point between the curve portion and the parallel portion while sharp in inclination in the area of a contact start point at a pointed end of the contact pin contact. The linear portion has a constant inclination angle. The insertion force of the pin contact increases linearly proportionally to the fitting depth of the pin contact into the socket contact while the linear portion is touching the contact spring portion, whereas the insertion force of the pin contact is kept constant regardless of the fitting depth while the curve portion is touching the contact spring portion of the socket contact at a point over the boundary point between the linear portion and the curve portion.
