Abstract: A connector which can improve reliability of electrical connection is provided. Accommodation recesses are formed to a plate-like terminal member, and a coil member accommodated in the accommodation recesses is retained to the terminal member, thereby allowing wire winding portions of the coil member to be deformed within the accommodation recesses when the winding wire portions are sandwiched between bottom faces of the accommodation recesses and a mating terminal. Consequently, the obliquely wound coil member is not likely to experience deformation other than fall over of ring portions, and/or is not likely to be displaced, improving contact between the coil member and both of the terminal member and the mating terminal. As a result, reliability of electrical connection can be improved.

The pressing member holds the contact segment of the female terminal that is inserted into the housing portion between the pressing member and the male terminals, elastically deforms the contact segment, and presses the contact segment toward the male terminal.
