description Provided is a surface-treated calcium carbonate filler for resins, characterized by comprising calcium carbonate particles, the surface of which has been treated with at least one surfactant (A) selected from a group consisting of saturated fatty acids, unsaturated fatty acids, alicyclic carboxylic acids, resin acids, and salts thereof and with at least one compound (B) having the ability to chelate an alkaline-earth metal, the compound (B) being selected from a group consisting of phosphonic acids, polycarboxylic acids, and salts thereof. The surface-treated calcium carbonate filler for resins deteriorates little with time, has satisfactory dispersibility in resins, and can give a sheet or film which has a satisfactory balance among durability, weatherability, strength, and thermal stability and is useful as a battery separator or light reflector.
