The present invention provides an ink composition or the like capable of providing a cured material with excellent balance between substrate adhesion and light shielding property while maintaining curability as an ink composition. According to an aspect of the present invention, an ink composition is provided. The ink composition includes a light shielding agent (A), a cationic polymerizable compound (B), a photoacid generator (C), and a sensitizer (D). A volumetric concentration of the light shielding agent (A) to a total solid content volume of the ink composition is 0.3% or more and 12% or less. The cationic polymerizable compound (B) includes a metal element-containing compound (B1) having a cationic polymerizable group and a hydrolysable group. A content of the metal element-containing compound (B1) is from 5 parts by mass or more and 80 parts by mass or less when a total solid content of the ink composition is 100 parts by mass. The sensitizer (D) includes a compound (D1) containing an anthracene skelet
