Disclosed is a board-to-board-type connector including: a female connector holder having an upper surface with an engagement opening with which a plurality of female terminals are engaged in symmetrical rows; and a male connector holder having an upper rim from which an engagement protrusion protrudes such that a plurality of male terminals are arranged in symmetrical rows and engaged with the engagement protrusion to form electrical contact with the female terminals, the male connector holding being fitted to the engagement opening of the female connector holder, wherein the female terminal includes a U-shaped receiving portion accommodated in the engagement opening and first stopper protrusions protruding toward an inside of the engagement opening from intermediate portions of both side surfaces of the receiving portion, the male terminal includes a U-shaped insertion portion formed along an outer peripheral surface of the engagement protrusion and second stopper protrusions symmetrically protruding toward an outside direction of the engagement protrusion from intermediate portions of both side surfaces of the insertion portion, and the female terminal is attached/detached to/from the male terminal by elastic deformation of the first stopper protrusions and the second stopper protrusions. Consequently, the board-to-board-type connector of the present invention is configured such that the female terminals are symmetrically deformed in the left and right directions when the female terminals are attached/detached to/from the male terminals. Thus, stresses being applied to the female terminals during attachment/detachment are distributed in the left and right directions, and therefore the engagement between the female terminals and the male terminals is stably maintained even when the connector is used over a long period of time.
