PROBLEM TO BE SOLVED: To provide hydraulic fluid for a shock absorber, having a small environmental load and improved with lubricating property and abrasion resistance, and the shock absorber equipped with the same. SOLUTION: This hydraulic fluid for the shock absorber is characterized by using base oil of any of a synthetic ester having≥1 ester bond in its molecule, or animal or plant oil as a main component, having biodegradability and≥8 and≤17 mm<SP>2</SP>/sec dynamic viscosity of the hydraulic fluid at 40°C.
