A tabular negative-pressure sheet 3 includes a baseplate 4, a sheet 5 with conduction grooves, a nonwoven cloth lamination outer layer 6, and a surface layer member 7. The baseplate 4 is a member as a base of the tabular negative-pressure sheet 3. In addition, the sheet 5 with conduction grooves is a member disposed on the outer side of the baseplate 4, and on the surface thereof, negative-pressure conduction grooves 8 are formed. In the tabular negative-pressure sheet 3, negative-pressure conduction grooves 8 are formed in a direction substantially perpendicular to a direction in which a strip 2 is threaded so that a negative pressure is generated as far as an end portion of the tabular negative-pressure sheet 3. |
