PROBLEM TO BE SOLVED: To provide an economical high viscosity liquid feed system wherein even if in a high viscosity liquid feed line, for example, a pressure fluctuation of 5 MPa-15 MPa is produced in a high-pressure side line, a low-pressure line can be adjusted to a certain pressure, for example, 1 MPa, further, two kinds of the conventional valves such as a pressure reducer and a shut-off valve, or an accumulator is not required, and the whole structure of a device can be simplified. SOLUTION: In the high viscosity liquid feed system in which a high viscosity liquid in a high viscosity liquid-containing tank 6 is sucked by a ram pump 1, and fed into the feed line S under high pressure, and at the same time, the high viscosity liquid is fed from a dispenser 2 through the feed line S to a work a fixed quantity at a time, a pressure-regulating valve 3 for a high viscosity liquid which reduces the high viscosity liquid of the high pressure flown in from a primary side, and regulates a secondary pressure regularly is provided on an upstream side of the dispenser 2 of the feed line S (at a position within a range not surpassing the permissive maximum pressure value at a discharging and stopping time of the dispenser), or directly on a suction opening 2a of the dispenser 2.
