Zusammenfassung:	To provide a polyisocyanate composition, a resin composition, and a resin cured product.SOLUTION: The polyisocyanate composition contains a polyisocyanate and has a weight average molecular weight of 500 or more and 10,000 or less and a viscosity at 25°C of 10,000 mPa s or less. The polyisocyanate is derived from an aliphatic or alicyclic diisocyanate and a polyol. The polyol has a number average molecular weight Mn of 150 or more and 840 or less and is bifunctional to trifunctional. The polyisocyanate has a molar ratio NCO/OH of isocyanate groups of the aliphatic or alicyclic diisocyanate to hydroxyl groups of the polyol of 2 or more and 30 or less.SELECTED DRAWING: None 【課題】ポリイソシアネート組成物、樹脂組成物及び樹脂硬化物の提供。【解決手段】ポリイソシアネートを含むポリイソシアネート組成物であって、前記ポリイソシアネート組成物は、重量平均分子量が５００以上１００００以下であり、２５℃粘度が１００００ｍＰａ・ｓ以下であって、前記ポリイソシアネートは、脂肪族ジイソシアネートまたは脂環族ジイソシアネートと、ポリオールと、から誘導され、前記ポリオールは、数平均分子量Ｍｎが１５０以上８４０以下であり、２官能以上３官能以下であり、前記ポリイソシアネートは、ポリオールの水酸基に対する脂肪族又は脂環族ジイソシアネートのイソシアネート基のモル比ＮＣＯ／ＯＨが２以上３０以下である、ポリイソシアネート組成物。【選択図】なし
