Miniature cell array structure and manufacturing method of miniaturized composite component using such a miniature cell array structure

A method of manufacturing a cell array structure, comprising:

• a first step of laminating a deformable layer capable of causing plastic deformation over a top surface of a substrate, said substrate being formed with a plurality of mutually separated depressions on said top surface, such that said deformable layer forms a mutually isolated space in each of said plural depressions;
• and
• a second step of extending said space for said plurality of depressions simultaneously in an upward direction of said substrate by causing plastic deformation in said deformable layer, such that a thickness of said deformable layer is increased in a state after said second step as compared with a state before said second step and such that there are formed a plurality of columnar cells respectively in correspondence to said plurality of depressions, said step of extending said space being conducted while restricting lateral expansion of said space in each of said plurality of columnar cells as a result of interference of adjacent spaces,
• wherein said second step includes a step of lowering a pressure of a space outside said deformable layer laminated on said substrate, said plastic deformation of said deformable layer being induced by a gas pressure in said plurality of depressions.
