An iso(thio)cyanate composition has excellent storage stability. The iso(thio)cyanate composition for an optical component includes an iso(thio)cyanate compound having two or more iso(thio)cyanate groups in a molecule, a phosphoric acid ester compound represented by general formula (1), and a phosphoric acid ester compound represented by general formula (2), a total amount of the phosphoric acid ester compounds being 1 ppm to 25,000 ppm, based on the mass of the iso(thio)cyanate compound.
