PURPOSE: A flux spreading device is provided to reduce the depth of a groove, where some of welding electrodes have passed, by spreading a flux in the groove so that the flux can cover wires of the welding electrodes stably when the wires pass the groove later on. CONSTITUTION: A flux spreading device comprises a flux storing unit(100), a main flux spreading unit(110), and a plurality of sub flux spreading units(131,133). The flux storing unit stores a flux(20). The main flux spreading unit, which is connected to the flux storing unit, spreads the flux on a predetermined spot of a base material. The sub flux spreading units spread some of the flux moving inside the main flux spreading unit through outlets aligned in a row in a welding direction. [Reference numerals] (AA) Welding direction
