Abstract: A surface-treated heavy calcium carbonate is provided which is useful for a film exactly controlled in its pore diameter and for easily hydrolyzable polyester resins. A heavy calcium carbonate is also provided which is compounded in a curable resin such as a one-component moisture-curable adhesive and a sealant either without any pre-drying treatment or by simple pre-drying treatment. A surface-treated heavy calcium carbonate satisfying 13,000≦A≦25,000, 0.8≦B≦3.0, C≧0.55, and 0≦D1≦1000, or 8,000≦A≦25,000, 0.8≦B≦15, 0≦C1≦1000, and 0≦C2≦150 wherein: A: specific surface area (cm2/g), B: average particle diameter (μm): 50% particle diameter (d50) (μm), C: 10% particle diameter (μm), D1, C1: water content at between 25° C. and 300° C. by a Karl-Fischer method (heating vaporization method) (ppm), and C2: water content at between 200° C. and 300° C. by the same method.
