Carbon fiber-reinforced plastic and production method therefor

A carbon fiber reinforced plastic comprising:

• a base portion comprising a plurality of stacked carbon fiber layers, the carbon fiber layers each comprising carbon fibers arranged at least in a single direction;
• a resin with which the base portion is impregnated;
• and
• a carbon yarn,
• wherein
• the carbon yarn is a yarn made by twisting two or more carbon nanotube yarns together, and the yarn made by twisting the two or more carbon nanotube yarns together is a Z-twist yarn,
• a thickness of each of the carbon fiber layers is in a range from 100 μm to 5000 μm,
• a diameter of the carbon yarn is in a range from 50 μm to 1000 μm, and
• the carbon yarn penetrates the plurality of carbon fiber layers.
