摘要

A negative electrode is provided to improve a charge and discharge efficiency of a battery, and to be easily manufactured. A negative electrode(80) has a negative electrode active material layer(82) provided on a negative electrode current collector(81). The negative electrode active material layer contains silicon as a negative electrode active material, or negative electrode active material particles(82A) made of a silicon-containing negative electrode active material, and a compound film(82B) having Si-O bonds and Si-N bonds which is present on at least a part of the surface of the negative electrode active material or negative electrode active material particles.
