PROBLEM TO BE SOLVED: To provide a pierced earring capable of being simply inserted into the small hole of an ear lobe and preventing the drop of a tube without requiring secondary machining by setting the tip diameter size of a post slightly smaller than the inlet hole diameter size of the through hole of a tube catch, and setting the base end diameter size of the post slightly larger than the inlet hole diameter size. SOLUTION: The tip diameter size L1 of a post 3 is set smaller than its base end diameter size L2, and the whole is formed into a tapered shape. A tube catch 4 is made of a raw material causing no metal allergy, and a flange section 5 is provided at its end section. A through hole 6 is bored on the tube catch 4, the inlet hole diameter size L3 of the through hole 6 is made equal to its outlet hole diameter size L4, or the inlet hole diameter size L3 is made slightly larger than the outlet hole diameter size L4. The tip diameter size L1 of the post 3 is formed slightly smaller than the inlet hole diameter size L3 of the through hole 6, and the base end diameter size L2 of the post 3 is formed slightly larger than the inlet hole diameter size L3 of the through hole 6. |
