PROBLEM TO BE SOLVED: To attain improvement of a charge/discharge characteristic, reliability and stability, by coating a peripheral part and/or a bending part of a surface in contact with a high polymer solid electrolyte of at least one electrode of the positive/negative electrodes, with an ion non-permeable material. SOLUTION: A peripheral part and/or bending part of a surface in contact with a high polymer solid electrolyte of a battery in at least one of positive/ negative electrodes are coated with an ion non-permeable material, without containing a metal material and electron conductive material, of 1×10<-8> S/cm or less electron conductivity and 10<-7> S/cm or less ion conductivity. In this way, in the case of cutting work of the battery, performance decrease according to a cut peripheral part and bending work is lessened, an outflow of a plasticizer and electrolyte, from a side surface of a laminated electrode/high polymer solid electrolyte layered product, can be impeded. |
