PROBLEM TO BE SOLVED: To provide a method of monitoring curing of a photocurable resin, which easily detects a curing state of a photocurable resin without adversely affecting the photocurable resin.SOLUTION: A method of monitoring curing of a photocurable resin includes the steps of: supplying a photocurable resin 1 including a liquid photocurable resin 1b and resin particles 1a having a refractive index equivalent to that of the photocurable resin 1b in a fully curing state, to an object 2; detecting brightness of the photocurable resin 1b, the resin particles 1a, and the boundary between them through an image while hardening the photocurable resin 1 with light irradiation for photocuring; comparing first brightness of at least one of the photocurable resin 1b and the resin particles 1a and second brightness of the boundary with each other; and determining that the more the photocurable resin 1 cures the smaller the difference in brightness is. |
