A welding structure of a press-formed part according to the present invention is a welding structure of a press formed part made by combining and joining two parts formed by press-forming and each having an opening portion on at least one side of a cross-section, while the opening portions face each other. A step portion 7 is provided by forming a bent projection 5 projecting outwardly on a tip end portion of a side wall portion 3a of a lower side part 3, partially or entirely on a joining surface. A tip end side of the step portion 7 is fitted into the opening portion of an upper side part 9, and the step portion 7 of the lower side part 3 and the tip end of a side wall portion 9a of the upper side part 9 are linearly joined by arc welding.
