Provided are a terminal silyl group resin composition having a low initial modulus of a cured product, capable of maintaining a low modulus even after a heating acceleration test, and excellent in storage stability before curing, and a method for producing the same. BET specific surface area surface-treated with a fatty acid calcium carbonate is in the range of 1m 2 / g~60m 2 / g, the alkali metal content is in the range of 500μg / g~2000μg / g, extracting with ethanol The free fatty acid calculated | required by (1) contains the surface treatment calcium carbonate which exists in the range of 1.8-2.5 mass%, and terminal silyl group resin, It is characterized by the above-mentioned. |
