A connector (C) is formed such that a plurality of terminal insertion holes (12), into which terminals crimped to end parts of wires (40) are inserted, are arranged side by side in a width direction of a terminal insertion surface part (11) on the terminal insertion surface part (11) of a connector housing (10), and includes a plurality of guiding portions (25), (26) and (27) provided side by side in the width direction of the terminal insertion surface part (11) in correspondence with the terminal insertion holes (12). The guiding portions (25), (26) and (27) are configured to guide the wires (40) having the terminals inserted into the terminal insertion holes (12) in a perpendicular direction until the wires (40) are separated from the terminal insertion surface part (11) by specified distances.
