PROBLEM TO BE SOLVED: To provide a reduced pressure treatment device in which an exhaust pipe can be prevented from breaking at disattachment, and in which the reduced pressure room can be worked into a desired shape. SOLUTION: An exhaust cup 10 is composed of the main body 100 which is in a rectangular parallelepiped state, and of which inside is worked in a prescribed shape, and a rectangular parallelepiped lid 101 placed on the main body 100. The main body 100 is provided with a differential exhaust part 102 which opens holes almost all over the contact face with the back-rest glass 203 in the PDP200, the main exhaust part 104 which is a through hole and which has an opening in the vicinity of the corner part 103, a tube-like differential exhaust system 105 which communicates with the differential exhaust part 102, the tube-like main exhaust system 106 which communicates with the main exhaust part 104, a stopper 107, and a coil-shaped filament 108 which is arranged in the main exhaust part 104 and which is put laterally. This main exhaust 104, when the main body 100 is mounted on the surface of the back-rest glass 203, has an opening on the upper face of the main body 100 so that the position of the glass tube 303 of the sealed part 300 can be recognized visually.
