Abstract
An electrode for secondary batteries according to one embodiment of the present invention is provided with a core body and a mixture layer that is formed on the core body. The mixture layer comprises a first mixture layer and a second mixture layer that is arranged on the first mixture layer. The tortuosity (τ2) of the second mixture layer is lower than the tortuosity (τ1) of the first mixture layer. The ratio (τ2/τ1) of the tortuosity (τ2) to the tortuosity (τ1) satisfies, for example, 0.3≤(τ2/τ1)<1.
