The method for measuring static pressure distribution between two bodies in contact is investigated by applying the electrodeposited copper foil with pyramidal micro projections. Namely, inserting the foil into contact surfaces of the elements, the depencency of the deformation of micro projectins on the magnitude of static pressure is examined by a laser microscpe. On the basis of the results obtained, the relationship between the real contact area of the foil A_r to the elements and the magnitude of static pressure is formulated. The pressure distribution occurred between the circular cylinder made of carbon steel and the brass with flat surface and that between steel and steel compressed each other was determined by A_r measured and this formula and the accuracy of this method was examined.
