1. A pressurizing suction-attachment table, comprising:
a porous body including a suction-attachment surface on which an object can be placed;
an elastic member directly or indirectly provided to the porous body;
a frame body that supports the porous body via the elastic member;
an aspiration space formed between the porous body and the frame body; and
an aspirator capable of aspirating the aspiration space to cause the object to be suction-attached to the suction-attachment surface,
wherein the porous body includes an opposite surface positioned on a side opposite to the suction-attachment surface,
wherein the frame body includes a receiving surface for receiving the opposite surface when the elastic member is elastically deformed due to pressurizing the object placed on the suction-attachment surface toward the suction-attachment surface,
wherein the elastic member is configured to be elastically deformed such that the opposite surface of the porous body comes into direct contact with the receiving surface of the frame body when the object on the suction-attachment surface is pressurized toward the suction-attachment surface, and
wherein when the opposite surface is received by the receiving surface, a reactive force from the porous body to the object that is being pressurized becomes uniform.
