A terminal including a wire connection portion formed with a slit for receiving an electric wire, wherein the wire connection portion comprises: a pair of positioning portions that are disposed with the slit therebetween, and determine the position of the electric wire in a direction of a width of the slit; a pair of corner portions (33; 133; 233; 333; 433) that are disposed with the slit therebetween, and scrape off insulation coating of the electric wire which is positioned by the pair of positioning portions; a pair of supporting portions that are disposed with the slit therebetween, and support a conductive portion of the electric wire from which the insulation coating has been scraped off, in a state held therebetween, and a cutout (36; 136; 236; 336; 436) which communicates with the slit, wherein the corner portion (33; 133; 233; 333; 433) is located at an end portion of the supporting portion toward the positioning portion, wherein a spacing (W20, W30) between the pair of supporting portions is smaller than a spacing between the pair of positioning portions, wherein: said pair of supporting portions include: a pair of first supporting area portions that are disposed with the slit therebetween, and are adjacent to the positioning portions, respectively; a pair of second supporting area portions that are disposed with the slit therebetween, and receive the conductive portion having passed between the pair of first supporting area portions; and a pair of third supporting area portions that are disposed with the slit therebetween, and guide the conductive portion having passed between the pair of first supporting area portions into between the pair of second supporting area portions, and wherein a spacing between the pair of second supporting area portions is smaller than a spacing between the pair of first supporting area portions, characterized in that the boundary line indicative of a boundary between the cutout (36; 136; 236; 336; 436) and the slit is parallel to a central axis of the slit, wherein the surface (33A; 133A; 233A; 333A; 433A) of the corner portion (33; 133; 233; 333; 433) toward the positioning portion and the inner surface (36A; 136A; 236A; 336A; 436A) of the cutout (36; 136; 236; 336; 436) are smoothly continuous with each other, and wherein the spacing between the pair of first supporting area portions is equal to the spacing between the pair of corner portions (33; 133; 233; 333; 433). a pair of positioning portions that are disposed with the slit therebetween, and determine the position of the electric wire in a direction of a width of the slit; a pair of corner portions (33; 133; 233; 333; 433) that are disposed with the slit therebetween, and scrape off insulation coating of the electric wire which is positioned by the pair of positioning portions; a pair of supporting portions that are disposed with the slit therebetween, and support a conductive portion of the electric wire from which the insulation coating has been scraped off, in a state held therebetween, and a cutout (36;

a pair of second supporting area portions that are disposed with the slit therebetween, and receive the conductive portion having passed between the pair of first supporting area portions; and a pair of third supporting area portions that are disposed with the slit therebetween, and guide the conductive portion having passed between the pair of first supporting area portions into between the pair of second supporting area portions, and said pair of supporting portions include: a pair of first supporting area portions that are disposed with the slit therebetween, and are adjacent to the positioning portions, respectively; a pair of second supporting area portions that are disposed with the slit therebetween, and receive the conductive portion having passed between the pair of first supporting area portions; and a pair of third supporting area portions that are disposed with the slit therebetween, and guide the conductive portion having passed between the pair of first supporting area portions into between the pair of second supporting area portions, and wherein a spacing between the pair of second supporting area portions is smaller than a spacing between the pair of first supporting area portions, characterized in that the boundary line indicative of a boundary between the cutout (36; 136; 236; 336; 436) and the slit is parallel to a central axis of the slit, wherein the surface (33A; 133A; 233A; 333A; 433A) of the corner portion (33; 133; 233; 333; 433) toward the positioning portion and the inner surface (36A; 136A; 236A; 336A; 436A) of the cutout (36; 136; 236; 336; 436) are smoothly continuous with each other, and wherein the spacing between the pair of first supporting area portions is equal to the spacing between the pair of corner portions (33; 133; 233; 333; 433).
