Summary:PROBLEM TO BE SOLVED: To provide a lithium secondary cell for mounting on a board, restrained from a reaction between the cell material like a positive electrode, a negative electrode, nonaqueous electrolyte liquid, and a separator caused by reflow or the like, when mounting the lithium secondary cell on the board, prevented from liquid leakage when the internal pressure of the cell is bigly increased, without big increase of internal resistance of the cell. SOLUTION: For the lithium secondary cell to be mounted on the board comprising a positive electrode 1, a negative electrode 2 made of an alloy containing lithium and aluminum, and nonaqueous electrolyte liquid composed of solvent and solute, the solvent contains sulfolane and 1,2-dimethoxyethane.
