Zusammenfassung:	To provide a polyurethane resin that exhibits good biocompatibility and is excellent in wet abrasion resistance and adhesion to various substrates.SOLUTION: The polyurethane resin includes a constitutional unit derived from a polyol (A), and a constitutional unit derived from a polyisocyanate (B). The constitutional unit derived from the polyol (A) includes a structure represented by the specified general formula (1). The polyisocyanate (B) includes an aliphatic polyisocyanate (b-1) or alicyclic polyisocyanate (b-2).SELECTED DRAWING: None 【課題】各種基材に対する密着性ならびに耐水摩擦性に優れ、良好な生体適合性を発現するポリウレタン樹脂を提供する事。【解決手段】ポリオール（Ａ）由来の構成単位とポリイソシアネート（Ｂ）由来の構成単位とを含むポリウレタン樹脂であって、ポリオール（Ａ）由来の構成単位が下記一般式(１)で表される構造を含み、ポリイソシアネート（Ｂ）が脂肪族ポリイソシアネート（ｂ−１）又は脂環族ポリイソシアネート（ｂ−２）を含むことを特徴とするポリウレタン樹脂。【選択図】なし
