PROBLEM TO BE SOLVED: To provide a pitch-based carbon short fiber filler and a composite molded material, which have high thermal conductance and high moldability. SOLUTION: The pitch-based carbon short fiber filler has a mean fiber length (L1) of 40μm or more but less than 80μm observed with an optical microscope, a closed graphene sheet by filler end face observation with a transmission electron microscope, and a substantially flat surface observed with a scanning electron microscope.
