Abstract: A magnetic block toy includes: a block body having, on outer surfaces thereof, coupling sections and non-coupling sections; and disk magnets provided inside the coupling sections in the block body. The block body includes magnet-holding portions where the disk magnets are arranged along the coupling sections and held in a circumferentially rotatable manner. Length of at least one side of the block body is equal to or longer than 30 millimeters and shorter than 40 millimeters. Only the coupling sections are provided with labels indicative of being capable of coupling to a coupling target. In the coupling sections, stepped portions are formed so that at least part of an outer-edge portion of each coupling section protrudes.

Abstract: It is an object of the present invention to provide an invention comprising the connective means for connecting the blocks in which at least two or more permanent magnets are arranged on each side of said blocks in a manner such that a magnetic polarity thereof is opposite to neighboring magnets, and the invention that can easily be built into the solid from the developed plane so as to produce the educational effect by appealing to the eye by constructing said permanent magnets in a biaxially anisotropic fashion whereby each other's edge faces or surfaces are attracted.
