A connector device includes a male connector and a female connector attached to and detached from each other by moving the male connector in a sliding direction relative to the female connector, the male connector including plug electrodes arrayed in an arraying direction perpendicular to the sliding direction, each plug electrode including a curved part formed at one end and bent in the arraying direction, and the female connector including jack electrodes arrayed in the arraying direction, each jack electrode corresponding to one of the plug electrodes and including a connection formed at one end and projecting in a direction parallel to the sliding direction, each connection including two resilient terminal portions, and when the male connector and the female connector are mutually fitted to each other, the curved part of each plug electrode is inserted and fitted between the two resilient terminal portions of a corresponding jack electrode.
