To provide a crystal structure (a bubble crystal body) of which the figure is beautiful, the mechanism is simple, and the manufacture is easy by reducing the sorts of spherical polyhedrons (bubble balls) so as to form a structure similar to a globular shape, and adopting bubble balls mainly of pentagon.

This bubble crystal body is roughly divided into three sorts respectively connecting together bubble ball lumps, bubble ball faces, bubble ball sides, there are an object colored on the surface, an object provided with an opening part to form a vessel, and an object integrated with inner or outer accompanied object. For example, along a cut corner icosahedron formed out of twelve pentagon and twenty hexagon, a twelve face bubble ball 1 is arranged on the center position of pentagon, and a fourteen face bubble ball 2 is arranged on the center position of hexagon. Further, twelve face bubble balls 1 are arranged on sixty apex positions, and it is used for the roof of a dome and a globular tool utilizing the formed hollow type globular bubble crystal body. Hereby, in addition to a customary block construction, a new assembling system is provided, and research and development of a solid construction and the progress can be expected.
