Beschreibung
Zusammenfassung:	Provided are a WC-based cemented carbide powder from which a WC-based cemented carbide member excellent in high thermal conductivity and high abrasion resistance can be manufactured, a WC-based cemented carbide member, and a manufacturing method for a WC-based cemented carbide member.The WC-based cemented carbide powder of the present invention includes WC, Cu, and at least one of Co, Fe, and Cr. The content of WC is equal to or more than 40 mass%, the content of at least one of Co, Fe, and Cr is equal to or more than 25 mass% and less than 60 mass%, and the ratio a/b of the content 'a' of Cu and the content 'b' of at least one of Co, Fe, and Cr satisfies 0.070 ≤ a/b ≤ 1.000.
