The right half of the housing portion 3 is a receiving portion 12 for inserting and connecting a female connector (not shown) by the side wall portions 8 and 9, the bottom guide portion 7 and the bridge portion 11. Here, for example, six terminals 2 are stamped from a plate material, and before the insert molding, the conductor portion 5 has a straight shape without being bent, and a connecting portion indicated by a two-dot chain line in FIG. After the insert molding, the connecting portion is punched and the left end is bent by press working after insert molding to obtain the shape shown in the drawing.

On the other hand, FIG. 1 and FIGS.
It is described according to the figure. In FIGS. 1 and 5 to 7, the second partial housing molded body 13 has terminals 14 arranged in a line along one plane, for example, a housing part 15 made of glass-containing PBT resin. It is configured by insert molding so as to protrude. A portion of each terminal 14 projecting rightward from the housing portion 15 in FIG. 1 constitutes a connection terminal portion 16, and a portion projecting leftward from the housing portion 15 constitutes a conductor portion 17.
