PROBLEM TO BE SOLVED: To provide an elastic staple capable of solving a problems that, although a conventional metallic staple needle can drill a hole easily, staple needles formed of soft raw materials such as paper, synthetic fibers or the like are available now because of a problem in safety and a needle holding means, an opening means for an object to be locked, a needle insertion means or the like of the soft needle having an unstable shape are extremely complicated and their operations are extremely troublesome. SOLUTION: The staple is constituted by inserting and pressing a group of needles formed of the soft materials and composed of a plurality of soft needles 4 into a cylindrical needle holding case 12, providing a front erected wall 13 covering a front face at a tip in the longitudinal direction of the needle holding case, providing an upper part opening 14 between the front erected wall and a tip of an upper face plate 8 and a lower part opening 15 between the front erected wall and a tip of a bottom face plate 11, operating a periphery covering blade 19 of a hole drilling guide implement 25 advancing toward the lower part opening from the upper part opening to drill a hole, and guiding and locking one soft needle on the tip side into an object K to be locked.
