Title: METHOD FOR MANUFACTURING CONTACT MEMBER, CONTACT MEMBER, AND VACUUM VALVE
Abstract:
This contact member is provided with a contact layer comprising a plate-shaped porous medium having a high-melting metal as a main component, into which an infiltrant having a low-melting metal as a main component has infiltrated; a contact layer support part comprising the infiltrant; and a contact-part-holding conductor. The porous medium has an opening part at the position which is the center of the contact layer, and the infiltrant is formed continuously from inside the opening part up to the contact-part-holding conductor.
