    • [Objectives] The present invention provides a non-aqueous secondary battery in which a material containing Si and O as constituent elements is used in a negative electrode. The present invention provides a non-aqueous secondary battery having good charge discharge cycle characteristics, and suppressing the battery swelling associated with the charge and the discharge. Also, the present invention relates to a negative electrode that can provide the non-aqueous secondary battery. [Solution] The negative electrode includes a negative electrode active material, including a composite of a material containing Si and O as constitution elements (atom ratio x of O to Si is 0.5≦x≦1.5) in combination with a carbon material, and graphite. The graphite has an average particle diameter dg (μm) of 4 to 20 μm. The material containing Si and O as constitution elements has an average particle diameter ds (μm) of 1 μm or more. The ratio ds/dg (i.e., ds to dg) is 0.05 to 1. The material containing Si and O as constitution elements has a crystallite diameter of 50 nm or less, the crystallite diameter is calculated from a half width at a (220) plane of Si obtained by an X-ray diffraction method, using Scherrer Formula. In 100 mass % of the composite of the material containing Si and O as constitution elements, and the carbon material, a ratio of the material containing Si and O as constitution elements is 70 to 95 mass %.
