Abstract: To form, on a ceramic member or a metal member, a thermal spray ceramic coating film which achieves both the quality of a ceramic coating film and gas barrier property, and with which a composite oxide having a melting point lower than the ambient temperature will not form when used as a coating film on a ceramic member or a metal member constituting a glass article manufacturing apparatus.A ceramic coating film-provided member comprising a ceramic member or a metal member and a thermal spray ceramic coating film formed on at least a part of the surface of the ceramic member or the metal member, wherein the thermal spray ceramic coating film contains Al2O3 and 12CaO.7Al2O3, and the weight ratio of CaO to Al2O3 (CaO/Al2O3) is more than 0.11 to 0.50.
