A lithium secondary battery is provided with: a power generating element accommodated in a flexible battery case (6), the power generating element including a negative electrode (2), a positive electrode (1), and a non-aqueous electrolyte. The negative electrode contains negative electrode active material particles composed of silicon and/or a silicon alloy. The positive electrode contains a positive electrode active material composed of a lithium-transition metal composite oxide. The non-aqueous electrolyte contains ions of at least one element selected from the group consisting of Co, Cu, Mg, Mn, Ni, Fe, and Zr.
