Patent ID: 8042648

Claim:
A material for processing comprising: an elastically deformable single thin plate comprising a plurality of through-holes, the elastically deformable single thin plate comprising: a first wave-like shape which is formed in a first direction and in which troughs and ridges are alternately connected in repetition, and a second wave-like shape which is formed in a second direction crossing the first direction and in which troughs and ridges are alternately connected in repetition, wherein the first wave-like shape has a corrugated shape in which the ridges each include a pair of side parts rising from the corresponding troughs and an apex part connected between the pair of side parts; wherein an apex length of the apex part along the first direction is defined as being longer than an opening length, along the first direction, between base parts of the pair of side parts; wherein the troughs and the ridges have the through-holes; wherein the ridges are formed to have a predetermined height with respect to the troughs; wherein the material for processing is attachable to a vibration generating member at a position a predetermined interval away therefrom; and wherein the ridges and troughs reduce vibration distribution on a surface of the material caused by the through-holes.
