ABSTRACT:
The inclination angle, in the conductor pattern end portion of a magnetic bubble memory element having a bubble diameter of up to 1.2 .mu.m, can be remarkably reduced by employing a polymer resin, having fluidity in a curing process, as the insulation film under the conductor pattern, so that the transfer margin is greatly improved.
