Claim:
An orthodontic buccal tube attached to a face of a tooth by glue, comprising: a base having a bonding face on one side of the buccal tube; a body having a slot into which an archwire is inserted in a middle of the body on a side opposite the base; and a glue anti-outflow step formed along an outer circumference of the bonding face at a predetermined height in a closed loop, the glue anti-outflow step preventing the glue applied to the bonding face from flowing out towards a boundary between the base and the tooth, wherein the bonding face includes a plurality of pimples arranged within an area surrounded by the glue anti-outflow step at regular intervals and at a predetermined height, wherein the plurality of pimples are divided into a central pimple that is located at a center of the bonding face and peripheral pimples that are located around the central pimple, and the central pimple is formed so as to have a larger contact area than each peripheral pimple without overlapping with an arrangement of the peripheral pimples, and wherein the central pimple has a height greater than the glue anti-outflow step and each peripheral pimple so that the separation starts from the central pimple when the buccal tube is removed from the face of the tooth; wherein the height of the pimples and the glue anti-outflow step is measured vertically from the bonding face.
