PURPOSE: A tetrahedral block structure and a manufacturing method thereof are provided to improve the diversity and safety by connecting tetrahedral blocks each other. CONSTITUTION: A tetrahedral block structure(11) comprises a tetrahedron block, a connecting projection(15), and a connecting groove(17). The tetrahedron block comprises a space(13) and four surfaces. The tetrahedron block is connected other tetrahedral blocks to form a construction structure. The connecting projection is formed on one or more surfaces among the four surfaces of the tetrahedron block. The connecting groove is formed in one or more other surfaces in which the connecting projection is not formed. |
