PROBLEM TO BE SOLVED: To prevent deforming of a seal surface that originates in generating of 'molding sink' at the time of resin forming. SOLUTION: A fleshless part 20 of the form, which an upper wall surface 16a of a cavity 12a is partially cut, is formed in a partition part 19 between the seal surface 14 of the perimeter of a connector housing 10, and the upper wall surface 16a, which sits back to back with the seal surface 14 in the cavity 12a. Therefore, even if the partition part 19 is fleshy, generation of the 'molding sink' is hard to occur at the time of mold forming, then, the modification of the seal surface 14 resulting from the 'molding sink' is prevented.
