To provide a light-curing resin composite, that can form an accurate minute convexoconcave pattern even if embossed at a relatively low temperature in a relatively short time, and prevent blocking at room temperature in the winding body with an uncured light curing resin layer formed on a supporting body and a winding body, a transfer foil, a minute projecting and recessed pattern forming method, and optical component.

The light curing resin composite is one including a hydrophobic silica particle in a binder resin having an optical polymerization functional group as an essential component with softening starting temperature lowered. It is used for forming the minute projecting and recessed pattern of the optical component.
