Abstract: A probe card used in a probing test machine which send and receive test signals into circuits through pads of a semiconductor chip, thereby examining the electrical characteristics of the circuits. The probe card comprises a supporting plate, a flexible printed circuit base including a flexible film base material supported by the supporting plate, circuits printed on the film base material being connected electrically to a tester, contactors connected electrically to the printed circuits and adapted to be brought into contact with the pads in equally corresponding relation, and a cushioning medium designed so as to back up a section in which the contactors are mounted. When the contactors are brought into contact with the pads, individually, the cushioning medium undergoes an elastic deformation, so that the contact between the contactors and the pads is improved.

Abstract: A self-hardenable material comprising a calcium phosphate having an atomic ratio of Ca/P of 1.4 to 1.6, a difficultly water-soluble inorganic fluoride, an organic or inorganic acid and water is provided.
