In the can lid, there is formed a protrusion protruding upward from the can lid in front of the can opening during manufacturing of the can lid, in which it is a collapsing protrusion where the protrusion elastically deforms into the can main body by depressing motion of the user and thereby enables forming of a concave section for easy insertion of the user's finger.
