The present invention provides a rubber composition for a studless tire, which can achieve sufficient abrasion resistance, performance on ice and snow, and wet grip performance in a balanced manner, and a studless tire having a tread produced from the above composition. The rubber composition for a studless tire contains a rubber component including natural rubber and butadiene rubber; aromatic oil; silica; and carbon black, wherein the total amount of the natural rubber and the butadiene rubber is 30% by mass or more based on 100% by mass of the rubber component, the amount of the aromatic oil is 12-85 parts by mass and the amount of the silica is 12-85 parts by mass, per 100 parts by mass of the rubber component, and the proportion of the silica is 45% by mass or more based on 100% by mass of the total of the silica and the carbon black.
