摘要:
The present invention discloses an alkaline dry cell with a high capacity having a superior liquid leak resistant property. In this alkaline dry cell, the thickness of the trunk portion of an external can is made thinner than 0.18 mm, and the thickness of the sealing edge portion of the external can is set to not less than 1.4 times the thickness of trunk portion. An anode terminal plate is used as a supporting member for a sealing member. Over the entire outer circumferential portion of the anode terminal plate is placed a curved portion having an average curvature radius of not more than 1 mm, which shows a virtually C-letter shape or an arc shape in its cross-section obtained by cutting the anode terminal plate through its center in the thickness direction.
