1. A wear resistant component comprising:
a matrix portion made of metal; and
a framework portion embedded in the matrix portion and higher in hardness than the matrix portion, wherein
the framework portion has a three-dimensional lattice structure formed with a plurality of bar-shaped members and has a shape that follows a shape of at least a portion of a surface of the matrix portion, and
the plurality of the bar-shaped members include a first bar-shaped member extending along a first direction, a second bar-shaped member extending along a second direction intersecting the first direction, and a third bar-shaped member extending along a third direction intersecting a plane including the first direction and the second direction.
