PROBLEM TO BE SOLVED: To provide pop-up cards capable of being developed from a flatly folded state to a three dimensional developed state by a simple operation and erected in the developed state on an installation surface such as a desk and allowing an interior image to be seen through from the front as a three-dimensional, layered image. SOLUTION: Under the constitution that middle ground surfaces 4a and 4b are formed through foldback lines 3a and 3b at the right and left of a foreground surface 2 provided on a transparent sheet 5, an upper cutting-in line 6a is provided on one middle ground surface of the transparent sheet while a lower cutting-in line 6b is provided in the other middle ground surface and then the respective middle ground surfaces are folded back towards their backs and, at the same time, the respective middle ground surfaces are brought into an intersect state by inserting mutually the upper cutting-in line and the lower cutting-in line of the respective middle ground surfaces and further the ends of the respective middle ground surfaces are connected with a background sheet, the foreground surface, the respective middle ground surfaces and the background sheet are turned from their flatly folded state to their three dimensionally developed state and the patterns drawn on the foreground surface, the respective middle ground surfaces and the background sheet are made to see through from the front.
