in a first graph showing results obtained by carrying out line analysis by using an energy dispersive X-ray spectrometer attached to a transmission electron microscope along a first direction going from the binder phase to the tungsten carbide particles adjacent to each other, in a coordinate system where an X axis is a distance from a position at which cobalt exhibits a maximum intensity, and a Y axis is a normalized intensity,

a maximum peak M of each of the first element is present between a peak W1 of tungsten closest to an origin and a further peak W2 of tungsten closest to the peak W1,

a ratio IB/IA of an intensity IB to a maximum peak intensity IA of the maximum peak M is 0.5 or less in each of the first element, and

the intensity IB is an intensity of the first element at a distance P2, which is a distance of 0.2 nm from a distance P1 at the maximum peak intensity IA toward an opposite side of the origin.
