PROBLEM TO BE SOLVED: To provide an inexpensively producible can in which a character, figure or symbol structured on its body part by an ink layer visually appears differently depending on whether the temperature is rising or dropping. SOLUTION: The outer surface of a can 10 body is formed with a non-thermochromism ink layer 11 which has the first color and structures the first figure. A thermochromism ink layer 12 is formed inside of the outer peripheral edge 11a of the layer 11 surface. The layer 12 structures the second figure and colors change reversibly from the first color to the second color due to the rise or drop of the temperature of the can 10. The color of the layer 12 changes from the first color to the second color due to the rise or drop of the temperature of the can, and thereby, the second figure develops to be seen visually and the first figure is seen with a change visually.
