PROBLEM TO BE SOLVED: To provide an assembled eraser to which a toy-like element is added, which can be assembled into a proper three-dimensional shape by easily and detachably fitting and connecting a plurality of blocks together, and which can be assembled in the original proper three-dimensional shape by replacing only the worn block in use. SOLUTION: In this assembled eraser, the plurality of blocks composed of nonangularly and three-dimensionally shaped erasers can be disassemblably assembled. At least either a hole part or a protrusion, which protrudes outward to be fitted into the hole part, is formed in each of the plurality of blocks. The blocks, wherein the hole part is formed, and the blocks, wherein the protrusion is formed, are mixed among the plurality of blocks. The blocks having the protrusion and the other blocks having the hole part among the plurality of blocks are disconnectably connected together by fitting the protrusion into the hole part.
