PURPOSE:To prevent the production of excess bubble by using the through hole technology so as to cross a hair pin conductor pattern at a proper location of at least two patterns in parallel with each other. CONSTITUTION:In the magnetic bubble generator formed on a bubble crystal 1 through the combination of a soft magnetic thin film pattern 5 and a hair pin conductor pattern 3, at least two patterns 3a, 3b adjacent to the hair pin conductor pattern 3 are crossed by using a through hole to form a loop. Since the hair pin conductor pattern 3 is formed as a loop by a conductor 9 in this way, a strong attracting magnetic field formed in giving a generated current (i) in the direction of arrow is generated in a part A only in the loop and a repulsion magnetic field is caused at a part B. Thus, the generated bubble is confined in the loop, then no branching is caused and production of excess bubble is prevented.
