A stapler of the present invention includes a retaining part having a staple pusher, a storing section that stores a staple, and a receiving base that bends leg parts after piercing the staple pushed out by the staple pusher through a sheet material to bind the sheet material with the staple. The staple includes left and right shoulder parts against which the staple pusher abuts, leg parts extending substantially perpendicularly from the shoulder parts and a pattern part having an arbitrary shape and provided between the left and right shoulder parts. The pattern part is inclined against the leg parts and the storing section is provided, on one side thereof, with a take-out opening of the staple that is large enough to allow the pattern part to pass.
