Claim Text:
1. An electrical connector comprising: a plurality of terminals disposed parallel with each other at predetermined intervals, each of the terminals having an intermediate portion between a tip end and a base end thereof; a case made of primary molding resin having a bottomed cylindrical fitting hood to which a mating connector is fitted, a bottomed cylindrical first fitting peripheral wall projected toward an opposite side where the fitting hood is projected, and a plurality of insertion holes that communicates between a bottom surface of the fitting hood and a bottom surface of the first fitting peripheral wall, while the intermediate portion is inserted; a holder made of primary molding resin having a bottomed cylindrical second fitting peripheral wall projected on a side where the second fitting peripheral wall overlaps with the first fitting peripheral wall and is fitted to an inner periphery of the first fitting peripheral wall, and a terminal holding section that supports the terminals by embedding each base end in a state where the intermediate portion is projected from a bottom surface of the second fitting peripheral wall; a sealant filled between the bottom surface of the first fitting peripheral wall and the bottom surface of the second fitting peripheral wall, the sealant seals gaps between the case or the holder and the terminals, and bonds the case and the holder; and a housing made of secondary molding resin that seals by covering at least the a fitting portion of the first fitting peripheral wall and the second fitting peripheral wall, and the holder; wherein, the holder has a second groove that opens at a front end of the second fitting peripheral wall and extends from an opening of the second groove to the bottom surface of the second fitting peripheral wall, and a sealed chamber formed between the bottom surfaces of the first fitting peripheral wall and the second groove, and the holder is communicated with each insertion hole; and the sealant is filled in the sealed chamber.
