1. A biopolymer crystallization method for crystallizing a biopolymer by impregnating a nanostructured substrate with a biopolymer-containing solution while applying electromagnetic waves,
wherein the nanostructured substrate comprises a base material, a base group fixed separately to the base material, and a metal layer group deposited on the base group, the base group is fixed separately to the base material, and
a ratio (SA/SB) of a geometric front area (SA) in terms of hemisphere on a total emission surface side of the metal layer group and a geometric back area (SB) on a total light-receiving surface side exceeds 1.
