Abstract
The present invention aims to provide an all-solid-state lithium ion secondary battery having a high reliability which does not have a decrease in battery capacity due to absorption of moisture in the air. The all-solid-state lithium ion secondary battery is provided with a battery body having an electrolyte layer between a positive electrode layer and a negative electrode layer, a pair of terminal electrodes respectively connected to the positive electrode layer and the negative electrode layer at both end portions of the battery body, and a moisture-proof layer disposed on surfaces excluding the surfaces to be the terminal electrodes, wherein the moisture-proof layer contains a cured product of a composition containing a polymer compound and metal compound particles.
