    • A problem to be solved by the present invention is to provide a urethane resin composition capable of forming a film having excellent adhesiveness to an adhesive, a putty material, and the like and having excellent durability such as moisture-heat resistance, hydrolysis resistance, and the like. The present invention relates to a urethane resin composition containing a urethane resin (C) produced by reacting a polyol (A) with a polyisocyanate (B), the polyol (A) containing a polyether polyol (a1), which has an oxyethylene structure (a1-1) and an oxyalkylene structure (a1-2) other than the oxyethylene structure (a1-1), and a polyoxytetramethylene glycol and/or a polycarbonatediol (a3), wherein the polyether polyol has a ratio by mass [(a1-1)/(a1-2)] of the oxyethylene structure (a1-1) to the oxyalkylene structure (a1-2) in a range of 3/7 to 9/1, and the ratio by mass of the polyether polyol (a1) is 10% by mass to 50% by mass.
