PROBLEM TO BE SOLVED: To provide a simple spot welding gun for welding a place difficult to set a gun tip. SOLUTION: The spot welding gun 11 is equipped with a first gun arm 14 crossing the pressing direction to works 6 lapping each other and extending and at the same time mounting and supporting a first electrode tip 31 extending in the pressing direction through a first shank 21 on the side face of a tip, a second gun arm 13 provided in parallel along the extending direction of the first gun arm 14, a first extending part 24 which bas been extended in almost the same direction as the extending direction of the second gun arm 13 by avoiding abutting on a base part 23 which has been freely removably mounted at the tip of the second gun arm 13 and a first shank 21 from the base part 23, a second extending part 25 being bent and formed almost in parallel to the extending direction of a first electrode tip 31 from the tip of the first extending part 24 and extending and a second shank 22 being bent and formed almost in parallel to the extending direction of a first extending part at the tip of the second extending part 25 and having a tip mounting part 26 mounting and supporting a second electrode tip 32 opposed to the first electrode tip 31.
