PROBLEM TO BE SOLVED: To provide a manufacturing method of a pressure sensitive adhesive sheet wherein a sheet body storing one movable contact body can be obtained while having good workability. SOLUTION: A storage hole 20 for storing a movable contact body 3 and an air hole forming part 22 communicating with the storage hole and having an edge 22a on the inside of the outline position of a sheet body 2 are formed by superposing a first pressure sensitive adhesive sheet 10 on a release sheet 1 and stamping them, a through hole 30 corresponding to the storage hole and the air hole forming part is formed in the release sheet, a second pressure adhesive sheet is superimposed on the top side of the first pressure sensitive adhesive sheet, only the first pressure sensitive adhesive sheet and the second pressure sensitive adhesive sheet are cut according to the outline shape of the sheet body, the release sheet, the first pressure sensitive adhesive sheet, and the second pressure sensitive adhesive sheet are stamped, and a communicating hole 23 communicating with the air hole forming part and the outline position of the sheet body is formed, and the air hole forming part of the first pressure sensitive adhesive sheet is thereby formed as an air hole 21 in communication with the storage hole and the outline position of the sheet body.
