PROBLEM TO BE SOLVED: To provide a three-dimensional puzzle in which the surface of different configuration from the cutting plane of a solid configuration is formed. SOLUTION: The three-dimensional puzzle has a puzzle body 10 having a cubical configuration in which the length of one side is r (r is the real number), p<SP>3</SP>solid crude pieces 101 which compose the puzzle body 10, are formed into the configuration of a cube in which the length of one side is r/p (p is an even number), and are mutually separable, the cutting plane of an equilateral triangle which passes (0, 0, r), (0, r, 0), and (r, 0, 0), the cutting plane of a rhombus which passes (0, 0, r), (0, r, r/2), (r, 0, r/2), and (r, r, 0), and the cutting plane of an equilateral triangle which passes (0 r, r), (r, 0, r), and (r, r, 0), the puzzle body 10 and a solid crude piece 101 are partitioned by each of the cutting planes, and on the other hand, one surface of the configuration of an isosceles triangle, a pentagon or a regular hexagon is formed by combining all or a part of the partitioned solid crude pieces 101.
