Patent ID: 7800001

Claim:
A probe assembly comprising a rigid wiring board, a block elastically supported on said rigid wiring board via a spring member, and a probe sheet having a probe sheet main body provided with a plurality of conductive paths buried in a flexible insulating synthetic resin film and electrically connected respectively to a plurality of wiring paths on said rigid wiring board and a plurality of contactors electrically connected respectively to said corresponding conductive paths and protruded from a contactor area on one surface of said probe sheet main body, said contactors operable to be brought into contact with electrodes of a device under test, wherein the other surface of said probe sheet main body is supported on a flat support surface of said block at a part corresponding to said contactor area wherein in said probe sheet main body is buried a plate-shaped member having higher rigidity than that of said synthetic resin film and restricting deformation of said contactor area.
