An end mill includes: a columnar tool body that rotates about a center axis; and outer peripheral cutting edges on an outer peripheral surface of the tool body, the outer peripheral cutting edges including a first outer peripheral cutting edge and a second outer peripheral cutting edge. A relief angle θ of the first outer peripheral cutting edge changes to increase in an axial direction of the tool body from a bottom face that is one end of the tool body. A relief angle θ of the second outer peripheral cutting edge changes to decrease in the axial direction from the bottom face.
