Abstract

A structure manufacturing method manufactures a structure including an expansion layer M 2 by expanding the expansion layer M 2 that is included in a print medium M and expands by heating. An electromagnetic wave-heat conversion material is formed on a first surface of the print medium M in density corresponding to a shape of a structure C 0 to be manufactured. Here, either the material is formed in lower density than density of the material in a first part of the expansion layer M 2 to be expanded to a first height H 1 and density of the material in a second part of the expansion layer M 2 to be expanded to a second height H 2 or the material is not formed, in a boundary region A 0 which is the first surface in a boundary part between the first part and the second part. The print medium M is then irradiated with electromagnetic waves.
