PROBLEM TO BE SOLVED: To provide a WC-based cemented carbide member joined by brazing, wherein brazed joining strength is improved. SOLUTION: The WC-based cemented carbide member 6 joined by brazing is characterized in that the joining face of the cemented carbide member 6 is a melting re-solidification layer 5, wherein the content of W by mass% is 85-95%, that R≤0.01 assuming R is a ratio (C/W) of C over W, and that 1≤T≤3 assuming Tμm is a thickness of the melting re-solidification layer 5.
