Abstract
There is provided an apparatusthat includes a pair of moldsandthat press together, heat, and weld an overlapping part of a plurality of film-like members, a pair of heater blocksandthat respectively support the pair of molds; a plurality of first support blocksthat are connected via a plurality of rod-like members, which midway include parts that restrict transmission of heat, to one heater block; a plurality of second support blocksthat are connected via the plurality of rod-like members to the other heater block; and a driving mechanismthat changes, via the support blocks, a gap between the pair of molds to press together the film-like members. The plurality of first support blocks include at least one movable support blockincluding a mechanismthat moves in a first direction relative to the driving mechanism corresponding to thermal deformation in the first direction of the heater block to be supported, and the plurality of second support blocks include at least one movable support block
