The present invention provides a polyisocyanate composition and the like that contains a polyisocyanate compound represented by general formula (III) (wherein the pluralities of R31 each independently represent an organic group, at least one of the pluralities of R31 is a group represented by general formula (V) (wherein each of the plurality of Y1 independently represents a single bond or the like, R51 represents a hydrogen atom or the like, and the wavy line indicates a bonding site) or the like, and in general formula (III), R32 represents a residue in which one hydroxyl group has been removed from a monohydric or higher alcohol), wherein the group represented by the general formula (V) is originated from a bis(2-isocyanoethyl)-2-isocyanatoglutarate or a lysine triisocyanate.
