A pair of male terminals (14, 14a) is protruded from a tip end of an inserting portion (13a) of a male connector (11). A female connector (12) is formed in a tube shape having a bottom capable of being fitted to an inserting portion (13b), and a pair of female terminals (15, 15a) is provided at the inner side of the bottom part (12a). Terminal portions (16) of the female terminals (15, 15a) are formed in a fork shape having an opening (18) arranged to oppose the male terminals (14, 14a). An acute angle portion (21) which bursts through a coating body (20a) of an FFC (20) is provided between the tip end portions of the fork-shape part (19), and a conductive wire connecting portion (22) which grips a conductive wire portion (20b) of the FFC (20) that has been burst through by the acute angle portion (21) is provided between the base end portions of the fork-shape part (19), and a terminal receptor (23) to which the male terminals (14, 14a) are inserted is provided between the middle portions of the fork-shape part (19).
