1. A production method for a three-dimensionally shaped object, comprising:
a step of producing a sheet by providing a thermally expansive layer on a main surface of a base on a side of a first base, the base including the first base and a second base that are laminated thereon;
a step of providing an electromagnetic wave heat conversion layer on a main surface of the base of the sheet on a side of the second base; and
an unevenness forming step of forming unevennesses on a surface of the sheet by causing the thermally expansive layer of a region corresponding to the electromagnetic wave heat conversion layer to distend by irradiating the electromagnetic wave heat conversion layer with electromagnetic waves of a predetermined wavelength,
wherein the first base and the second base have elasticities different from each other.
