An electrical connector includes a connector main body made of an insulating material for attaching an end portion of a pair of single wires untwisted at an end portion of a twisted pair cable; and a shell member to hold the untwisted portion. The shell member includes a base portion made of a conductive material to dispose the connector main body at the front end side and the untwisted portion at the basal end side; a cable holding portion made of a conductive material to hold the single wires at the untwisted portion for positioning the single wires parallel to each other and close or contact to each other; and a cover portion provided on the base portion to have at least the untwisted portion and the cable holding portion between the cover portion and base portion.
