Abstract: An Al-based intermetallic compound in which a eutectic crystal type Al-CuMn intermetallic compound dispersion phase is dispersed in an Al-Cu intermetallic compound matrix phase. The content of Mn as a eutectic crystal-forming element contained in the dispersion phase is set in a range of from 5% by weight (inclusive) to 30% by weight (inclusive).

In another embodiment, the Al-based intermetallic compound contains peritectic type Al-based intermetallic dispersion phase, such as formed by Ta, dispersed in the intermetallic compound matrix phase.
