PROBLEM TO BE SOLVED: To provide a filter cap for a liquid receiver of large size capable of integrally forming a filter and a stopper body with a synthetic resin without assembling them, and stabilizing the shape by reducing the amount of synthetic resin while keeping strength. SOLUTION: In this filter cap for the liquid receiver of large size, comprising the stopper body 21 inserted from an opening portion 12 of a cylindrical liquid receiver main body 11 constituting the liquid receiver for gas-liquid separation of a heat medium, and closing the opening portion 12, and the filter 22 disposed on a tip face of the stopper body 21 in the liquid receiver main body 11 and capturing impurities in the heat medium supplied to the liquid receiver main body 11, the stopper body 21 and the filter 22 are integrally formed with the synthetic resin, the stopper body 21 has a cylindrical portion 21b having a fitting insertion groove 21a of an O-ring on its outer peripheral face, and a reinforcement member 23 made of aluminum alloy such as metal is integrally molded and fixed to a back portion side of the fitting insertion groove 21a of the cylindrical portion 21b.
