An automotive frame part is provided to a side portion of an automotive body and absorbs crashworthiness energy by bending upon receiving a crashworthiness load from a side of the automotive body. The automotive frame part includes: a member having a hat-shaped cross section or a U-shaped cross section and including a top portion, and a pair of side wall portions that are continuous from the top portion via punch shoulder R portions; and resin that is coated on or patched to an internal surface of the member having the hat-shaped cross section member or the U-shaped cross section. The resin extends at least to a predetermined range toward the top portion and the side wall portions on both sides of the punch shoulder R portions, and is adhered, after heating, to the internal surface at an adhesive strength of 10 MPa or higher at a room temperature.
