The present invention provides a urethane resin composition containing a urethane resin which is a product of reaction between a polyol (A) including a polycarbonate polyol (a1), and a polyisocyanate (B). The urethane resin composition is characterized in that the polycarbonate polyol (a1) is obtained using a hydroxy compound (C) including a hydroxy compound (c1) represented by general formula (1) as a raw material. The urethane resin composition can be used to form a urethane resin-molded article having excellent solvent resistance and hydrolysis resistance.
