PURPOSE:To mount a sliding member with a high reliability, by bond-casting with an aluminum alloy a connection metal member of a ceramic pad member serving as the sliding member, the metal member being connected at a back surface of the pad member. CONSTITUTION:A ceramic member 1A formed of Si3N4 for example is provided at one end of an aluminum alloy base 3 to form a sliding surface. A bonding W alloy member 2A having a substantially sectorial shape in cross section projects from a back surface of the ceramic member and is bonded thereto by an activated metal process. The bonding W alloy member 2A is bond-cast with an aluminum alloy to form a desired rocker arm. The activated metal process is conducted by heating at 850 deg.C for 10min with use of a Ti-Ag-Cu alloy as an insert. According to this constitution, the wetting of the aluminum alloy in bond-casting is improved, and it is therefore possible to well bond the ceramic member 1A to the base 3. Thus, the strength and reliability may be increased.
