According to an embodiment of the present invention, a reinforcing member for cold forming comprises a blank member, and a reinforcing patch member provided to cover at least a portion of the blank member and coupled to the blank member by a plurality of welding parts. The welding part is formed at position when a heat effect part formed around the welding part is in circumscribed contact with the edge of the reinforcing patch member or at position at least further inside the reinforcing patch member than in this case, but can be formed at position when the center point of the welding part is in contact with the heat effect part of the other adjacent welding part or at least a position further apart from the other welding part than in this case.
