To provide a metal material employed in an outdoor usable component, and capable of achieving weight reduction and/or strength enhancement.SOLUTION: A metal material of a crank arm 21 includes an outermost surface 27, and a base material 29 having a compression stress application part 35. The compression stress application part 35 has a first layer 37 defined to range from the outermost surface 27 to a first depth P1 in a thickness direction of the metal material 25. The first depth P1 is a dimension to a position of 0.1 mm down from the outermost surface 27 in a thickness direction. A first minimal compression stress of the first layer 37 is equal to or larger than 250 MPa.SELECTED DRAWING: Figure 5
