Accordingly, a fibrillating step of a paper making material is achieved by an explosive crushing step. Alternatively, the step is achieved by a mixing step of a paper making material and a liquid, a material micro-fabricating step of applying a pressure to a mixed solution obtained by the mixing step so as to pass through an orifice and thereafter run into a device wall, and a paper making step including the micro-fabricated material.
