PROBLEM TO BE SOLVED: To enable a male connector in a connector for an accessory to be reliably inserted into a female connector.SOLUTION: A male connector 100 consists of a rod-like body 110, and a groove 111 is formed in the rod-like body 110. In a region before the groove 111 of the rod-like body 110, a thick part 110A, a thin part 110B and a thick part 110 C are formed in this order from a leading end side. Since contact resistance is generated when the thick part 110A on the leading end side is inserted into a female connector 520, a user is able to confirm that the male connector 100 is being inserted into the female connector 520 in a reliable manner when the user fits the male connector 100 into the female connector 520 at the back of the neck, for example. |
