The negative electrode of the secondary battery includes a negative electrode current collector and a negative electrode active material layer that is supported by the negative electrode current collector and that contains a negative electrode active material. The negative electrode active material layer includes an upper layer and includes a lower layer. The negative electrode active material contains at least a graphite particle, and a Si-containing particle in which a carbon and a Si are compounded to be composite. A response area size of the negative electrode active material contained in the upper layer is smaller than a response area size of the negative electrode active material contained in the lower layer, and a Si amount of a first Si-containing particle contained in the upper layer is smaller than a Si amount of a second Si-containing particle contained in the lower layer.
A negative electrode for a secondary battery, comprising:
