The invention as a one to multiple stacked carbon fibers with one or a plurality of carbon fiber bundle comprising a plurality of carbon fibers aligned in one direction, the carbon fiber layer, the surface and / or at least a portion of the end face of the carbon fiber layer At the same time, it made of a graphite conversion unit, a carbon fiber layer, a preform using it, characterized in that G-band and D-band intensity ratio (the intensity of D-band intensity / G band) of 0.3 or less in the obtained from the Raman spectrum of the graphite conversion unit, and to methods for their preparation. Carbon fiber layer, or can be easily machined to the end face of the preform, and without this from happening, the carbon fibers shedding from the end surface, it is possible to realize a trimming process with high accuracy. Therefore, they, can be short, also placed in the forming mold with high precision, and also, it becomes possible to omit the deburring operation, low cost, it can realize a reduction in production time.
