摘要：
An electric contact member which is excellent in voltage-proof performance and melt-resistant performance and excellent in mass productivity, and a method of manufacturing thereof, and a vacuum interrupter, a vacuum circuit breaker and a load-break switch for a road side transformer using thereof. The contact member is composed of a base member made of high conductive metal, and a contact layer made of refractory metal and high conductive metal, and the contact layer is formed of a plurality of thermal sprayed layers.
