MANUFACTURING METHOD OF BATTERY, AND INSPECTION METHOD OF BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a battery capable of judging by non-destruction appropriateness of welding at a welding portion of a current collector member to a battery case or a first member to a second member, and to provide an inspection method of a battery capable of judging by non-destruction the appropriateness of welding. SOLUTION: The battery 100 is provided with a power generating element 150, a current collector member 130 which is made of metal and connected to the power generating element, and a battery case 110 which houses these and is made of metal and has a sealing member 115 including a current collector welding portion 115X in which the current collector member 130 is welded. The manufacturing method is provided with a measuring process in which a supersonic vibration portion 115S of the sealing member 115 is applied supersonic vibration MW and the supersonic vibration MW transmitted through the current collector welding portion 115X is received at a supersonic reception portion 115T, and a judgement process in which the appropriateness of welding of the current collector portion 115X is judged based on the intensity C of the supersonic vibration MW received.
