PURPOSE: A tacker staple having a barb formed is provided to prevent a gap between materials from being easily widened as a tack easily comes off from the material. CONSTITUTION: A tack constituting a main body(1) has the same shape as the existing taker staple. A barb(3) is protrudently formed by cutting a side face of the tack into a regular size. Herein, the barb is formed in each zigzag shape at a regular interval. Thereby, when the main body is about to come off by a load or force after inserted in a timber(4), the barb regularly contacts the structure inside the timber.
