ABSTRACT:
An object of the present invention is to provide carbon fibers which have a high conductivity, readily form a network in a matrix and are suitable for use in a radiating member as well as a molded product thereof. The present invention is pitch-based carbon fibers which are obtained from mesophase pitch and have an average fiber diameter (AD) of 5 to 20 μm, a ratio (CVADvalue) of the degree of filament diameter distribution to average fiber diameter (AD) of 5 to 15, a number average fiber length (NAL) of 25 to 500 μm, a volume average fiber length (VAL) of 55 to 750 μm and a value obtained by dividing the volume average fiber length (VAL) by the number average fiber length (NAL) of 1.02 to 1.50, and a manufacturing method and molded product thereof.
