摘要： The present application discloses an insulating sheet of a cylindrical battery, including an insulating sheet body. A tab through hole or a tab notch is formed in the insulating sheet body, the tab through hole or the tab notch is arranged to be eccentric. The insulating sheet of the cylindrical battery further includes a blind hole or a through hole formed in a middle portion of the insulating sheet body, and further includes a metal sheet. The metal sheet covers on an opening at an end of the blind hole or the through hole and/or is arranged in the blind hole or the through hole. A surface of the metal sheet protrudes or is flush with the opening of the blind hole or the through hole, and a thickness of the metal sheet in the through hole is smaller than a depth of the through hole.
