Zusammenfassung:	PURPOSE:To eliminate any damage at the time of manufacturing and to improve durability and heat insulating property at the time of using by forming a porous thermal-spraying layer hang high heat resistance and acid resistance and low heat conductivity composed of metal powder as cast-in on inner wall of an exhaust port. CONSTITUTION:As the porous thermal-spraying layer 4 formed on the inner wall of the exhaust part is composed of the metal powder or the metal powder and ceramic powder, the thermal-spraying layer 4 has elongation property together with the heat insulating property at the same as or more than the ceramic. Therefore, even if stress caused by heat shock and heat fatigue is acted, as the stress is relaxed by deforming, this has excellent durability without developing any damage of crack, etc.
