Abstract

A problem to be solved by the present invention is to provide a polyurethane film that offers both soft texture and high strength. The present invention relates to a polyurethane film obtained by solidifying a polyurethane (A) obtained by reacting a polyol (a1) including an aliphatic polyester polyol having an anionic group (a1-1), and a polyester polyol (a1-2) other than the aliphatic polyester polyol (a1-1) with a polyisocyanate (a2), using a metal salt, in which the polyurethane (A) has an aromatic structure in the range of 500 mmol/kg to 2,000 mmol/kg with respect to the entire polyurethane (A).
