PROBLEM TO BE SOLVED: To provide a button type air zinc battery of high power type whose quality is stable. SOLUTION: Even when a large water repellent film of air permeability is acted, natural light is intercepted and ultraviolet rays are irradiated by coloring air spread paper by a fluorescent dye, it becomes possible to detect the position of air spread paper after a water repellent film is inserted using an image sensor. Air spread paper sorts out and eliminates what is protruded from a positive electrode housing bottom recess. Thereby, the button type air zinc battery whose quality is stable in high power can be provided. COPYRIGHT: (C)2006,JPO&NCIPI |
