Abstract
A disclosed method for producing a hollow cell array structure includes a first step of layering a deformable material capable of being plastically deformed under a predetermined condition on a first substrate, the first substrate having plural, mutually separated depressions in a surface thereof, such that the deformable material forms mutually isolated spaces in the corresponding depressions; a second step of expanding the spaces in the plural depressions by inducing a gas pressure of the spaces while extending the deformable material on the first substrate, such that plural hollow cells are simultaneously formed in correspondence to the plural depressions in predetermined directions; and a third step of selectively solidifying portions of the plural hollow cells by selectively applying ultraviolet rays thereto.
