Method of manufacturing porous body, porous body, method of manufacturing device, device, method of manufacturing wiring structure, and wiring structure

A method of manufacturing a porous body comprising:

• applying a photocurable composition including a condensing gas and a polymerizable compound to a substrate or a mold;
• sandwiching the photocurable composition between the substrate and the mold and then irradiating the photocurable composition with light to cure the photocurable composition;
• and
• releasing the mold from a surface of the cured photocurable composition;
• wherein the method further comprises, before the applying, leaving the photocurable composition to stand for a predetermined period of time in a closed space in which the condensing gas is present;
• the condensing gas is a gas having a pressure of 0.05 to 1 MPa for achieving gas-liquid equilibrium at 25° C.;
• the polymerizable compound has a ΔSP, which is represented by the following Equation (1), of 15 (J/cm3)1/2 or less:
• ΔSP=|solubility parameter (SP) value of polymerizable compound−SP value of condensing gas included in photocurable composition|. . . (1);
• a second condensing gas is introduced between the mold and the substrate at the sandwiching;
• and
• the second condensing gas is different from the condensing gas dissolved in the photocurable composition.
