A method of manufacturing an inorganic waste solidification shield structure that shields a compacted formation obtained by filling in banking material containing inorganic waste at a final disposal site, characterized by comprising: a preprocessing step that secures a first space and a second space by partitioning, in the horizontal direction, a space which is to be filled with the banking material and which is demarcated by walls at the final disposal site; a first step that forms a first compacted formation by pouring and compacting a type-B banking material containing a type-B inorganic waste with high concentrations of hazardous substances over the first space partitioned by the preprocessing step; a second step that forms a second compacted formation by pouring and compacting a type-A banking material containing a type-A inorganic waste with low concentrations of hazardous substances over the first compacted formation obtained by the first step; wherein the low concentrations of hazardous substances of the type-A inorganic waste are less than the high concentrations of hazardous substances of the type-B inorganic waste; a third step that forms a third compacted formation by removing the partition between the first space and the second space after the second compacted formation is formed by the second step, and pouring and compacting the type-A banking material into the second space; a fourth step that forms an upper primary shield layer by evenly spreading and compacting gravel over the second compacted formation and the third compacted formation obtained by the second step and the third step, forms an upper capping layer by evenly spreading a covering material consisting of a cement mixture over the upper primary shield layer, and evenly spreading and compacting gravel onto the evenly spread covering material, forms an upper secondary shield layer by evenly spreading gravel over the upper capping layer, and integrates the upper primary shield layer, the upper capping layer, and the upper secondary shield layer by placing a weight on top of the upper secondary shield layer and allowing a curing period to elapse; and a fifth step that, after the upper primary shield layer, the upper capping layer, and the upper secondary shield layer are integrated by the fourth step, forms a lateral primary shield layer by applying a coating to a lateral face of the third compacted formation that is exposed by removing the walls, forms a lateral capping layer by applying a coating to the lateral primary shield layer, and forms a lateral secondary shield layer by applying a coating to the lateral capping layer. a preprocessing step that secures a first space and a second space by partitioning, in the horizontal direction, a space which is to be filled with the banking material and which is demarcated by walls at the final disposal site;
