PURPOSE: To provide a deformable card-shaped toy capable of deforming its configuration by constituting a plurality of folding-developing parts in which some parts as a whole are formed into the form of a card to constitute a base plate when they are folded and the other parts are developed to constitute figures supported on the base plate.

CONSTITUTION: In the use of a deformable card-shaped toy 1, a folding- developing part 11 in the form of a card is developed about the fulcrum of a hinge 12 and a folding-developing part 4 is developed and folded about the fulcrum of a hinge 3 to erect relative to a developing part 2 and fold a generally triangular folding-developing part 13 provided on a folding-developing part 4 about the fulcrum of a hinge 14. A folding-developing part 5 is developed downward about the fulcrum of a support shaft 6 and a folding-developing part 9 provided on the lower portion of said part 5 is developed downward about the fulcrum of a support shaft 10. Thus, said toy 1 is changed into a doll playing base ball. Since said toy 1 is formed into the form of a card as a whole when it is folded, it conveniently does not occupy so much space. Further, the description 15 concerning the doll is indicated on the upper surface of a folding-developing part 2 for learning.
