Abstract
Provided are a composite wear-resistant member which can be manufactured with a lowered sintering temperature, and thus can prevent the carbonization of a material around super hard particles such as diamond; and a method for manufacturing the member. The member, characterized in that it comprises hard particles comprising diamond particles and WC particles and an iron group metal containing phosphorus as a binding material, wherein the content of phosphorus is 0.01 to 2.0 wt % relative to the total weight of the WC particles and the binding material.
