Abstract
A welding state inspection method for ultrasonic-welded plate-like members includes the steps of measuring energy that has been transmitted to an anvil when ultrasonic-welding a plurality of plate-like members stacked on the anvil while pressing a horn that vibrates against the plate-like members; and determining a quality of a welding state of the plate-like members on the basis of the energy measured in the measuring step.
