Abstract
An aluminum-alloy sheet for a bus bar has a chemical composition containing Mg: 0.3%-0.9% (mass %, likewise below), Si: 0.2%-1.2%, Cu: 0.2% or less, and Fe: 0.5% or less, the remainder being Al and unavoidable impurities. In addition, acicular particles containing Mg and Si are present in the Al matrix at 900-4,000 particles/μm. In addition, Fe-based particles present in the above-mentioned Al matrix have an average circle-equivalent diameter of 5 μm or less, and the number of particles having a circle-equivalent diameter of more than 2 μm is 10,000 particles/mmor less.
