To provide a resin composition for gel coat which can form a gel coat of which at least one property, preferably all the properties, selected from among scratch resistance, durability, and formability has been improved according to the use.

This resin composition contains a resin component comprising a polymer and a monomer as the main ingredient. The resin component contains component A: 5-40 wt.% (meth)acrylic polymer and component B: 60-95 wt.% monofunctional (meth)acrylic monomer. Preferably, the resin component further contains component C: 5-40 wt.% aromatic vinyl monomer and component D: 1-20 wt.% polyfunctional monomer.
