摘要

[Problem] To provide a CFRP sheet that is not only excellent in terms of mechanical strength such as tensile strength, but also excellent in terms of visible surface design. [Solution] This CFRP sheet is constituted by forming a transparent resin layer C on the outer side of a surface layer from a CFRP layer S, wherein: the CFRP layer S is formed from multiple UD sheet pieces, each yielded from continuous fiber shaped carbon fibers F·F… arranged to be aligned in the length direction and in this state adhered to one another and turned into a single body with a matrix resin M, the UD sheet pieces being adhered by the matrix resin M while the fiber direction of each of the sheet pieces is in a randomly oriented state and the sheet pieces are in a state of being arranged in a two-dimensional orientation in such a manner as to overlap one another; and, in contrast to the UD sheet pieces P·Q… in the back surface layer or the middle layer of the CFRP layer S, which have a rectangular shape, the UD sheet pieces P·P… in the surface layer are constituted by including sheet pieces that are smaller in mean thickness than the UD sheet pieces Q in the back surface layer or the middle layer, and at least partially distorted into a non-rectangular shape.
