the plug fixing portion includes a pair of shoulder portions on both side surfaces between the plug fixing portion and the projecting portion, and

the plug fixing portion and the projecting portion are in direct contact with the second side wall portion of the plug housing.

9. A connector manufacturing method for manufacturing the connector according to claim 5 , comprising the following steps of:

placing the connector fitting on a lower mold by a fixing jig;

covering the lower mold, on which the connector fitting is placed, with an upper mold configured to be able to house the connector fitting therein, thereby placing the connector fitting inside the upper mold, and pressing the pair of shoulder portions of the connector fitting by the upper mold;

injecting an insulating resin for forming the housing into a space between the lower mold and the upper mold;

curing the resin; and

removing the upper mold and the lower mold, and taking out the housing that is formed by curing the resin and holds the connector fitting.
