PROBLEM TO BE SOLVED: To provide a solid oily cosmetic that does not cause sweating by blending a high molecular weight and low viscosity oil. SOLUTION: A polyglycerin fatty acid ester oil having a viscosity of 500 mPa · S or less at room temperature and a volume change per weight by temperature change of 0.85 mm 3 / (g · ° C.) or less as an antiperspirant in solid oily cosmetics. Is blended. Such polyglycerin fatty acid ester oils include decaglycerin capric acid ester having a hydroxyl value of 20 to 70, decaglycerin caprylic acid ester having a hydroxyl value of 20 to 70, decaglycerin caprylic acid / capric acid mixed fatty acid ester having a hydroxyl value of 20 to 70, A dodecaglycerin caprylic acid ester having a hydroxyl value of 20 to 70, a dodecaglycerin capric acid ester having a hydroxyl value of 20 to 70, and a dodecaglycerin caprylic acid / capric acid mixed fatty acid ester having a hydroxyl value of 20 to 70 are preferred.
