A battery is provided. The battery includes an electrolytic solution, a positive electrode and a negative electrode. The negative electrode has a negative electrode active material layer containing a carbon material and having a thickness per one face of 70 mum or more and not more than 120 mum. The electrolytic solution contains a solvent containing 15% by mass or more and not more than 30% by mass of a cyclic carbonate represented by the following formula (1): wherein R1 to R4 each independently represents hydrogen, a halogen, an alkyl group or a halogenated alkyl group. A mass content ratio (B/A) of a halogenated cyclic carbonate (B % by mass) contained in the cyclic carbonate (A % by mass) which is represented by the formula (1) being from 0.5 to 1.0
