Abstract: By working a grabbing portion by a charged particle beam of FIB or the like, the grabbing portion in parallel with the beam can be formed, and also dust adhered to the grabbing portion is removed. When a small sample represented by a TEM sample is fabricated by being cut out by etching by a charged particle beam and is carried at inside of an apparatus of irradiating a charged particle beam, the sample is etched in a direction of irradiating the charged particle beam, and therefore, a mechanism pinched by a grabbing face of a grabbing portion can be worked in a direction the same as that in working the sample, and therefore, a change in an attitude can be reduced when the sample and the grabbing face are fabricated by parallel faces.
