1. A method for attaching a flat-shaped battery used in an apparatus that has a substrate and is to be attached to a rotary portion,the flat-shaped battery being a combination of a positive electrode can and a negative electrode can opposed to each other, andthe method comprising:

  • connecting the substrate and the flat-shaped battery to each other via a terminal;

    wherein one of the positive electrode can and the negative electrode can is opposed to an inner or outer side of the substrate with respect to a rotation center of the rotary portion;

    the negative electrode can has a different amount of deformation than the positive electrode can, wherein the deformation is caused by bulging at a time of expansion of the flat-shaped battery; and

    the can having the smaller amount of deformation is opposed to the substrate; and

    burying the substrate and the flat-shaped battery in resin.
