PURPOSE: To raise the will of setting a jigsaw puzzle by allowing at least one puzzle piece to have a one-division printed sheet to form a specific figure, including an ultraviolet-sensitive light-emitting substance in the form of microcapsule in a curable synthetic resin layer provided on the upper surface, and thereby permitting the emission color of the piece to serve as a mark. CONSTITUTION: At least one piece 2 of a jigsaw puzzle has one-division printed sheet 4 to form specific figure on the surface, and a curable synthetic resin layer 5 is furnished on the upper surface of this printed sheet 4, and an ultraviolet-sensitive light-emitting substance 6 in the form of microcapsule is included in the layer 4. Therefore, the light-emitting substance 6 reacts and emits light immediately when ultraviolet rays of the solar beam are cast on the layer 5 of the piece 2. When the puzzle pieces 2 are to be set, the emission color serves as a mark, and at the completion of the puzzle, the part of the layer 5 with the total figure is seen as if it was embossed.
