PROBLEM TO BE SOLVED: To provide a curable composition which shows high elongation after heat resistance treatment even if blended with a hollow body.SOLUTION: A curable composition includes a hollow body which is surface treated using a heavy calcium carbonate or a synthesis calcium carbonate, having an average particle diameter of ≤0.15 μm. The cured material of the composition shows high elongation even after heat resistance treatment at 90°C. |
