To provide a negative ion generating accessory which keeps appearance quality over a long period of time and takes negative ions into the body since a negative ion generating coating material is not easily discolored and is not easily peeled off, and its manufacturing method.

To the ring body 12 of a bracelet 10, a first negative ion generating body 16 and a second negative ion generating body 18 are attached. The negative ion generating coating material cylindrical attaching body 20 of the first negative ion generating body 16 and the negative ion generating coating material bottomed attaching body 22 of the second negative ion generating body 18 are coated with the negative ion generating coating material 24. The negative ion generating coating material 24 is applied by being sprayed to the negative ion generating coating material cylindrical attaching body 20 and the negative ion generating coating material bottomed attaching body 22 for two or more times and then baked for 20 to 30 minutes at a temperature of 140 to 150C.
