A fusion welding device include: a first holder, having a first face, and adapted to hold at least an outer peripheral face of an end portion of a first work in a state where the first work is movable in a longitudinal direction thereof; a second holder, having a second face opposed to the first face, and adapted to hold at least an outer peripheral face of an end portion of a second work in a state where the second work is movable in a longitudinal direction thereof; a heater, operable to heat the first and second works; a first and second movers, adapted to move the first and second holders in such directions that the first and second faces come close to or apart from each other; and a third mover, adapted to move the first and second holders in synchronization with each other in a direction along the first and second faces. The first and second holders are moved by the third mover in a state where the first and second faces are in contact with each other, whereby end faces of the end portions of the first and second works are pressed to each other in the longitudinal directions thereof in the first and second holders.
