A coaxial connector device which comprises an insulating base 12 placed on a circuit board, a signal-joining contacting conductor 13 fixed to the insulating base 12 with a contact connecting portion 13a and a signal-connecting portion 13b, and a grounding contacting conductor 15 fixed to the insulating base 12 with a cylindrical ide wall portion 15a surrounding the contact connecting portion 13a, ground-connecting portions 15b and connecting portions 15c for connecting the cylindrical side wall portion 15a to the ground-connecting portions 15b, wherein a groove 16 is formed between the signal-joining contacting conductor 13 and the grounding contacting conductor 15 on the insulating base 12 and at least one of the connecting portions 15c is deformed for becoming distant from the signal-joining contacting conductor 13, and with which miniaturization on the whole can be compatible with presentation of desirable and appropriate characteristic impedance which is of a value matching with characteristic impedance presented by a coaxial cable connected to a mating coaxial connector device operative to engage with the coaxial connector device. |
