A terminal plate is formed with a wide portion and a narrow portion. The wide portion, to be insert-molded by a housing of a synthetic resin, is opened by an elongate blank hole having an inner peripheral surface parallel with a side shape thereof, thereby forming two divisional parts on the both sides thereof. The divisional part is given by a width s 1 narrower than a width s 2 of the narrow portion, wherein the total width (s 1x2 ) of the two divisional parts is made equal to the width s 2 of the narrow portion. Grooves can be formed on the main and back surfaces of the divisional parts.
