End mill

An end mill comprising:

• a cutting edge portion and a shank, which are rotated about a central axis,
• wherein the end mill includes a bottom cutting edge located on a tip surface of the cutting edge portion, and a peripheral cutting edge located on an outer peripheral surface of the cutting edge portion,
• the bottom cutting edge has a bottom cutting edge outer peripheral portion that extends from an outer peripheral end of the bottom cutting edge to the shank side toward an inner side in a radial direction at an inclination angle of 3° or less with respect to a plane orthogonal to the central axis,
• a flank angle of a bottom cutting edge outer peripheral portion primary flank face adjacent to the bottom cutting edge outer peripheral portion is larger than a flank angle of a peripheral cutting edge primary flank face adjacent to the peripheral cutting edge, and
• a width of the bottom cutting edge outer peripheral portion primary flank face is larger than a width of the peripheral cutting edge primary flank face.
