A coin type (button type) electrochemical cell is configured of a negative electrode can configuring a negative electrode side and a positive electrode can configuring a positive electrode side. Then, the negative electrode can and the positive electrode can are formed of non-magnetic stainless steel which does not have magnetic properties due to plastic processing. Specifically, the negative electrode can and the positive electrode can are formed by using high manganese stainless steel or SUS305 having a high nickel (Ni) content. In this way, the negative electrode can and the positive electrode can are formed of non-magnetic stainless steel which maintains non-magnetic properties even after being processed into the shape of a coin, and thus it is possible to provide a non-magnetic electrochemical cell, and as a result thereof, it is possible to provide an electrochemical cell which is not affected even at the time of being arranged in the vicinity of a magnet. |
