    • PROBLEM TO BE SOLVED: To provide a multilayer substrate and a probe card capable of substantially suppressing thermal deformation and being manufactured at low costs without having to use special materials.
      SOLUTION: The probe card 10 is provided with a circuit board 12 connected in such a way as to be in a free electrical continuity with a probe 11A to be in electrical contact with a wafer W. The circuit board 12 is provided with a substrate layer 12A and surface layers 12B and 12C layered on both surfaces of the substrate layer 12A. The surface layers 12B and 12C have a larger coefficient of thermal expansion than that of the substrate layer 12A. The surface layer 12B is provided with grooves 12F for dividing the lower surface layer 12B into a plurality of pieces. By this invention, it is possible to solve the problem that multilayer printed circuit boards for conventional-type uses have required to select materials (glass fiber cloth) for forming electrical insulation layers so that the coefficient of thermal expansion in planar directions of an electric insulation layer supporting a conductor circuit 1 may be smaller than that in planar directions of an electric insulation layer supporting a conductor circuit 2, required special specifications, and raised manufacturing costs while being capable of suppressing thermal deformation.
