To provide a sheet body-holding device capable of avoiding the occurrence of an outward appearance defect and deformation.
A sheet body holding part 2 sucks and holds an intermediate body 100 when regions A1 shown by broken lines are cut off by irradiation with laser beam, from regions A2 disposed at the periphery of the regions A1 and shown by a broken line, and includes a suction stage 20 in which a ventilation groove 55 is provided between a center projection part 51 and right and left projection parts 51, a ventilation groove 62 is provided between the respective projection parts 51 and a frame part 41, and a suction hole 46 connected to a negative pressure supply source and sucking air in the ventilation grooves 55, 62 and a jet hole 47 connected to a positive pressure supply source and jetting air into the suction holes 52, 62 are formed in the ventilation grooves 55, 62. While the air is jetted from the jet hole 47 into the ventilation grooves 55, 62, the air is sucked from the suction holes 44, 46, and 52 to hold the intermediate body 100 to the projection parts 51 and frame part 41.
