PROBLEM TO BE SOLVED: To facilitate an opening operation of a can top.SOLUTION: A tab 3 fixed by a snap 2 and extending in a cross direction, is provided on an approximately center of a can top plate 1. An antiskid hole 3a as a target of a position where is pushed down by fingers, is provided in the vicinity of a rear end of the tab 3 closest to a seaming part 4 of the can top plate 1. A folding part 3b on which stress is concentrated, and thickness of a portion is made thin in a uniform state over whole width of the tab 3, so that the folding part is folded easily between the snap 2 and the rear end, is provided. The rear end is provided on one side of the tab 3, and a top pushing end 3c is provided on an opposite front end. The can top plate 1 comprises a fulcrum 5 for supporting the can top plate 1 and the tab 3 in an approximately parallel state between the rear end of the tab 3 and the folding part 3b on an apex projecting from the can top plate 1 in a mountain-state.
