A connector which can improve reliability of electrical connection is provided. Accommodation recesses (211, 212) are formed to a plate-like terminal member (2A), and a coil member 3A accommodated inthe accommodation recesses (211, 212) is retained to the terminal member (2A), thereby allowing wire winding portions (31, 32) of the coil member (3A) to be deformed within the accommodation recesses(211, 212) when the winding wire portions (31, 32) are sandwiched between bottom faces of the accommodation recesses (211, 212) and a mating terminal (100). Consequently, the obliquely wound coil member (3A) is not likely to experience deformation other than fall over of ring portions (311, 321), and/or is not likely to be displaced, improving contact between the coil member and both of the terminal member (2A) and the mating terminal (100). As a result, reliability of electrical connection can be improved.
