    Abstract: It is an object to extend the service life of a thermal-sprayed coating thermal-sprayed onto a molten metal resistant member and to prevent adhesion of a molten metal. In the molten metal resistant member, a contact portion coming into contact with a molten metal including Zn and/or Al has been covered with the thermal-sprayed coating. The thermal-sprayed coating is formed by using thermal-spraying oxide-based ceramic particles having an average particle diameter as a median diameter of 10 ?m or smaller. The thermal-spraying particles are thermal-sprayed at a high flying particle velocity of 1,000 m/sec or higher with only the surfaces of the flying thermal-spraying particles being in a semi-molten state and the inside of the particles being in a solid state. The resistance to corrosion by a molten metal, insulating properties, the resistance to washing with acids, and the ability to prevent adhesion of the molten metal are thereby improved.
