  • Publication number: 20190084268
    Abstract: A sheet 1 of the present invention is a sheet including a first main surface 1a and a second main surface 2a having a plurality of protruding portions 2. The sheet 1 includes a first resin-impregnated fiber sheet 11, a second resin-impregnated fiber sheet 12, and a resin composition layer 13. The first resin-impregnated fiber sheet 11 forms the first main surface 1a. The second resin-impregnated fiber sheet 12 forms the second main surface 1b. The resin composition layer 13 fills space between the first resin-impregnated fiber sheet 11 and the second resin-impregnated fiber sheet 12. The melting viscosity of resin contained in the first and second resin-impregnated fiber sheets 11 and 12 at a temperature of 250° C. and a shear rate of 100 s?1 is lower than the melting viscosity of resin contained in the resin composition layer 13 under the same conditions.
