Abstract
A coating fluid holding member including a porous molded body which is formed of heat-resistant fibers (or a mixture of heat-resistant fibers and a filler) bound to each other with a binder, has intercommunicating pores having an average pore size of 1 to 500 .mu.m, and has a porosity of 20 to 90%, and a coating fluid holding member including a porous molded body which is formed of heat-resistant fibers bound to each other with a binder, contains fine intercommunicating interstices between fibers and uniformly distributed pores having a diameter of 0.05 to 2 mm, and has a porosity of 30 to 90%. The holding member has a high fluid holding capacity for its volume and releases the coating fluid, such as a parting agent, an oil or a coating compound, in a stable manner for an extended period of time.
