Provided is an electromagnetic chuck mounting structure capable of tightly and fixedly mounting an electromagnetic chuck on a table without fluctuation, having light weight, and making a low profile when an electromagnetic chuck is mounted on the table. The structure includes: a mounting groove recessed on an upper surface of the table and located inward of an edge of the table; a plurality of mounting holes formed at regular intervals on the mounting groove to fix the electromagnetic chucks to be mounted; and an adhesive filled and cured on the mounting groove and between the mounted electromagnetic chucks, wherein each of the electromagnetic chucks is fixedly fastened to each of the mounting holes by one fastening bolt, such that an upper surface of each electromagnetic chuck is aligned on a same plane with the upper surface of the table or protrudes from the upper surface of the table.
