Provided is a photocurable composition that contains a polymerizable monomer (A), a spherical filler (B) having an average particle size within the range of 230-1000 nm, and a polymerization initiator (C), the photocurable composition being such that: 90% or more of the individual particles that constitute the spherical filler (B) are within a range of ±5% of the average particle size; the polymerizable monomer (A) and the spherical filler (B) satisfy condition (X1) represented by formula (1): nP<nF (where nP represents the refractive index at 25° C. of a polymer obtained by polymerizing the polymerizable monomer (A) and nF represents the refractive index at 25° C. of the spherical filler (B)); and the polymerization initiator (C) includes a photosensitizing compound (C1), a tertiary amine compound (C2), and a photoacid generator (C3). |
