Patent ID: 7541820

Claim:
A probe card for inspecting electric characteristics of an inspection object, comprising: a contactor supporting probes on one surface at a side of the inspection object; a circuit board which is opposed to the other surface of said contactor and electrically connected to said contactor; and a connector which is interposed between the other surface of said contactor and said circuit board, electrically connects said contactor and said circuit board, and has elasticity, wherein said connector is formed so that elasticity of a part near a central side becomes smaller than that of an outer peripheral side of said contactor, wherein said connector is formed into a sheet shape which is in contact with the other surface of said contactor, and said connector is formed so that the elasticity becomes smaller stepwise in a direction from the outer peripheral side of said contactor toward the central side of said contactor, and in said connector, regions differing in elasticity are formed in a shape of concentric circles with a center of said contactor as a center of the circles in a plane view.
