1. A separation method for steviol glycosides, comprising:
loading a solution including two or more types of steviol glycosides to a separation medium; and
allowing a solvent A to flow through the separation medium such that at least two types of steviol glycosides in the steviol glycosides are separated,
wherein the separation medium comprises polyethyleneimine immobilized to porous particles of a (meth)acrylic polymer having a crosslinked structure, a diol structure, and a hydroxyl group.
