摘要： A vacuum valve which has a contact material having a constituent of high electrical conductivity such as Cu and an anti-arcing constituent including Cr in which particles whose particle size is in the range 0.1.about.150 .mu.m represent at least 90 volume %, and a ratio defined by the formula (.alpha..sub.900 -.alpha..sub.50).times.100/(.alpha..sub.900) for this contact material has a value of 8-12% and is the coefficient of thermal expansion of the contact material .alpha..sub.50 is the coefficient of thermal expansion of the contact material at 50.degree. C. The formation of channels generated at the interfaces of the Cr particles and the Cu matrix after undergoing the brazing step is suppressed, enabling the static withstand-voltage, contact resistance, and the breaking performance characteristics of the vacuum valve to be stabilized.
