An embodiment of a probe sheet enabling to restrict misalignment of the posture of each contactor accurately positioned on a probe sheet main body caused by deformation of the probe sheet main body is provided. The probe sheet comprises a probe sheet main body having a flexible insulating synthetic resin film and conductive paths buried in the synthetic resin film and a plurality of contactors formed to be protruded from a contactor area on one surface of the probe sheet main body and connected to the conductive paths. In the probe sheet main body is buried a plate-shaped member having higher rigidity than that of the synthetic resin film and restricting deformation of the contactor area.
