In order to reduce the probability that an electrode of a connector and a terminal part of a printed substrate are broken, this connector is provided with openings including a void, respectively, in at least one of surfaces perpendicular to generating lines of two prismatic surfaces facing each other with the void therebetween and having parallel generating lines, and at least one of surfaces parallel to the generating lines, and is equipped with: a first member which is disposed in the void, and performs a first movement that is a movement in a direction parallel to the generating lines; a second member which, following the first member, performs a second movement that is a movement in a direction corresponding to the direction of the movement of the first member between respectively predetermined first point and second point.
