PROBLEM TO BE SOLVED: To provide a method for measuring interface tension and surface tension of a low concentration surfactant, a highly volatile solvent, a corrosive sample, or the like, accurately with high reproducibility using an equipment for measuring surface tension or interface tension of a liquid sample. SOLUTION: In a liquid drop measuring method using a liquid sample feeder fixed with a shielding part for preventing intrusion of a sample into the gap between a push rod and the inner wall of a tubular body, residual liquid drop is removed forcibly after a liquid drop is formed and measured and then next analysis is started.
