Provided is a secondary battery, which can maintain cycle characteristics at a room temperature, and which can suppress deterioration of the cycle characteristics in the cases where the secondary battery is used at a high temperature. This secondary battery is provided with a positive electrode containing a positive-electrode active material, a negative electrode containing a negative-electrode active material, and an electrolyte solution. The secondary battery is characterized in that: the positive electrode and/or the negative electrode contains a binding agent, which has an organic portion configured of a resin, and an inorganic portion configured of silica, and which contains an organic-inorganic hybrid material that binds the positive-electrode active material and/or the negative-electrode active material; and the electrolyte solution contains fluorine-containing cyclic carbonate containing at least one fluorine atom. |
