Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a production method of a structural member by forming a coating which has high ductility, denseness and adhesion and low porosity on a high m.p. material. SOLUTION: In a production method of a structural member used in environment contg. the atmosphere or a gas at a high temp. over 250 deg.C or in an aq. solution environment at a high temp. over 100 deg.C, a coating material contg. ceramic particles is plasma-sprayed onto the surface of the structural member at a particle temp. of >=2000 deg.C and a particle speed of >=600 m/sec.
