Abstract
A hollow structure forming substrate includes: a surface on which a plastic-deformation film is formed by using a plastic-deformable material; a plurality of regularly-arranged gas-retaining spaces; a plurality of gas leading-out parts each having a first opening which faces corresponding one of the gas-retaining spaces and a second opening which faces the surface, the gas leading-out parts leads out gas retained in the gas-retaining spaces toward the surface under depressurized environmental condition; and a plurality of infiltration preventing spaces each provided in a space between corresponding one of the first openings and corresponding one of the second openings, in which the infiltration preventing spaces prevent infiltration of the plastic-deformable material from the surface into the gas-retaining spaces.
