PURPOSE:To attain the application of a guard rail in a multi-layer conductor sheet current drive type magnetic bubble element, by arranging the end of conductor sheets of each layer with a shift and providing a recess pattern for each end. CONSTITUTION:Each end 15 of conductor layers 12, 13 is shifted with a little shift. Further, the multi-layer construction has a garnet magnetic film 21, a conductor sheet 22, an end 23 of a sheet 13, an end 24 of a sheet 12, a recess pattern 25 provided at the end of the sheet 13, and a recess pattern 26 provided at the end of the sheet 12. As a result, an induced magnetic field produced at the sheet end is produced in the direction that magnetic bubbles are dirven to the outside of the sheet, and unnecessary bubbles are not invaded from the outside of the sheet. |
