A magnetic bubble element which is useful as an image information processing element. A thin film made of a magnetic bubble forming material has a plurality of wedge-formed patterns made of a non-magnetostriction soft magnetic thin film is formed on the upper surface of the thin film 16. A conductor grating comprising two undulating conductor patterns are provided each cycle of the undulation in both conductor patterns defining a wider pitch and a narrower pitch, each of the wedge-formed patterns being disposed over the corresponding part of one of the two conductor patterns defining the narrower pitch in a manner such that the apex portion and the bottom portion of each wedge shaped pattern extend into the parts forming the wider pitch.
