PROBLEM TO BE SOLVED: To provide a surface-treated calcium carbonate-additive material which is compounded in a resin and gives a resin composition having excellent thixotropy, slump resistance, storage stability, adhesive property, etc. SOLUTION: A surface on a calcium carbonate additive-material is treated by an aliphatic acid glycerin ester wherein in the aliphatic acid glycerin ester represented by general formula (1) [X1 , X2 , X3 are each RCOO- or OH-, R is a group represented by Cx H2x+1 , Cy H2y-1 , Cz H2z-3 or Cw H2w-5 (x is an integer of >=0, y is an integer of >=2, z is an integer of >=3 and w is an integer of >=4)], 50-95% of the total number of X1 , X2 and X3 are a stearic acid residue and its 50-5% are a palmitic acid resin.
