Abstract

There is provided a specimen and a current measuring method. Prepregs (P1 to P8) containing conductive fibers are laminated, and release films (F1 to F7) are interposed between prepreg layers so as to extend from one end to the center of the prepregs. The prepregs are heated under pressure to shape a composite material. Discrete conductive wires Wi (i = 1 to 8) that pass a measurement current are connected to end surfaces of the layers on the side where the release films are interposed. A common conductive wire Wc to pass the measurement current is connected to a surface of one of an uppermost layer and a lowermost layer at an end of the composite material on the opposite side. A current is passed between the common conductive wire and the discrete conductive wires. Currents in the layers are sequentially or simultaneously measured using an ammeter.
