PROBLEM TO BE SOLVED: To provide an apparatus for producing a sheet-fused body, in which when the width direction of an object to be conveyed is irradiated with a laser beam, an energy loss of the laser beam can be reduced.SOLUTION: An apparatus 20 for producing the sheet-fused body includes: an irradiation head 35 having a lens 351; a supporting member 21 for conveying a belt-like sheet laminate 10; and pressing member 24 for keeping the sheet laminate 10 in a pressurized state. The supporting member 21 has a slit-shaped opening 27 through which the laser beam 30 can pass. A taper 211, the mutual distance of which is made wider on the side of the irradiation head 35 than that of which on the side of the pressing member 24, is arranged on both ends 21e of the supporting member 21 for forming the opening 27. In the apparatus 20 for producing the sheet-fused body, the sheet laminate 10 of the pressurized state is irradiated with the laser beam 30 along the opening 27, the sheet laminate thus irradiated is divided and the edge of the divided sheet laminate is fused in an overlapped state to produce the sheet-fused body 3 having the sealed edge 4. |
