In the press-sintering step, the resultant mixture is pressure-molded under a pressing pressure of 1-4 t/cmso as to give a molded article, and the molded article is subsequently sintered by maintaining the same at a temperature of 1,100-1,200°C for 1-2 h in a heating furnace so as to give a calcined article. In the Cu infiltration step, a thin Cu plate is placed on the calcined article and maintained at a temperature of 1,100-1,200°C for 1-2 h in a heating furnace so as to induce liquid-phase sintering of Cu and its infiltration into the calcined article.
