摘要: An aluminum base composite material contains an aluminum polycrystal body being a polycrystal body of a plurality of aluminum base material phases partitioned by a grain boundary, a carbon nanotube part being formed of a carbon nanotube or an aggregate thereof and being dispersed in at least one aluminum base material phase, and an alumina part being formed of alumina and being dispersed in at least one aluminum base material phase. The carbon nanotube preferably has a sphere-equivalent diameter from 10 nm to 300 nm, and the number of the carbon nanotube part that is present in a cross-sectional area of 200 μm2 of the aluminum base composite material is preferably one or more.
