Abstract: A contact tip for welding includes: a tip case; a power supply tip that is housed in the tip case and supplies power to a welding wire supplied from a side close to one end of the power supply tip while holding the welding wire at another end opposite to the one end; and a guide that presses the power supply tip from the side close to the one end and houses the power supply tip in the tip case, in which the power supply tip has a shape in which an outer diameter from a press point pressed by the guide to a fulcrum in contact with the tip case increases from the press point toward the fulcrum, and the power supply tip is rotated about the fulcrum by pressing of the guide to hold the welding wire at the other end.
