Abstract

The particle size distribution calculated from measurement of graphite particles forming a filler by a laser diffraction method is controlled so that the accumulated value of graphite particles with a particle size of 5 µm or less is 10% or less and preferably, 5% or less, the accumulated value of graphite particles with a particle size of 100 µm or more is 10% or less, and the accumulated value of graphite particles with a particle size of from 10 to 40 µm is 60% or more, and the graphite particles with a particle size of from 12 to 20 µm is 40% or more of the whole.
