Abstract
Provided is a stereolithographic resin composition that suppresses sedimentation of the filler during shaping, has good handleability, and has high thermal conductance of the cured product. A stereolithographic resin composition containing a photocurable resin and a filler, wherein the filler is a metal-coated particle having a base particle including a polymer material and having a metal layer coating the surface of the base particle, and a density of the metal-coated particle is 1.5 g/cm3 to 4.0 g/cm3.
