In addition, as shown in FIG. 2, an inclined surface 42 is formed on the resin 23 that integrally molds the housing case 3 and the internal terminals 6 a, 6 b, and 7. In the inclined surface 42, the height of the resin 23 in FIG. 2 (the height in the direction of arrow A in the figure) becomes lower in the extending direction of the internal terminals 6a, 6b, 7 (in the direction of arrow B in the figure).
