The present invention is an unsaturated polyester resin composition comprising an unsaturated polyester (a), a monomer (b) having one polymerizable carbon-carbon double bond, a monomer (c) having two or more of (meth)acrylate groups, a filler (d) having high thermal conductivity, a glass fiber (e), a low profile additive (f), a curing agent (g), and a polymerization inhibitor (h), wherein the ratio by weight of the ingredient (b) to the ingredient (c) is from 50:50 to 75:25 and the unsaturated polyester resin composition comprises 400 to 1400 parts by weight of the ingredient (d) based on the total 100 parts by weight of the ingredients (a), (b), and (c). This unsaturated polyester resin composition has excellent curing properties without losing storage stability which can be used to provide a cured product having a low mold shrinkage ratio and high thermal conductivity.

A packaging container comprises an openable outer case and a bag for packaging a resin material in the outer case. The bag is partially turned back at fold portions so that part of the bag is turned inside out, and at least part of the out-turned part is fixed as a fixing part to any part other than the bag. The inner surfaces of the bag at the fold portions are placed in contact with each other, forming a contact portion, to seal the resin material. The contact portion is placed in correspondence with an openable part of an opening flap of the outer case.
