PROBLEM TO BE SOLVED: To provide a highly thermally conductive pitch-based carbon short fiber filler having high moldability and productivity, and to provide a composite molding material. SOLUTION: The pitch-based carbon short fiber filler has >12 to≤20μm average fiber diameter (D1) observed under an optical microscope, the percentage of the fiber diameter dispersion (S1) based on the average fiber diameter (D1) within the range of 3-20%, a closed graphene sheet in observation of a filler end face under a transmission type electron microscope, and a substantially flat surface observed under a scanning electron microscope.
