Molded article and hollow tube

A method for manufacturing a molded article comprising a molded article main body, and a coating film covering a surface of the molded article main body, the coating film adhering to the molded article main body, the method comprising:

• a process to prepare the molded article main body;
• a process to coat a liquid rubber composition on a surface of the molded article main body and form a coating film;
• and
• a process to cure the coating film by heating the coating film by an infrared heater and form the coating film,
• wherein the molded article main body comprises an infra-red absorbing component comprising at least one of titanium oxide, cobalt oxide, iron oxide, manganese oxide, chromium oxide, copper oxide, nickel oxide, and carbon, and the coating film comprises a rubber composition including a thermal curing rubber component, wherein a static friction coefficient on a surface of the coating film is 0.5 or less, and
• wherein an adhesion strength between the molded article main body and the coating film is 0.30 MPa or more.
