To provide a sub-stage pressure device capable of applying the uniform pressure to an area of an arbitrary size.

A pressure unit is composed of a main pressure part and a plurality of sub-pressure parts. The main pressure part has the function of applying the pressure to the whole part of a specified area. The sub-pressure parts are provided corresponding to each of divided areas when the specified area is divided into a plurality of parts, and have the function of independently applying the pressure to each divided area. For example, in an electric conduction inspection device in which a sheet-like conductive rubber is arranged between a device of arbitrary size to be tested and a sensor part, this pressure device can be used for applying the pressure to the conductive rubber.
