Abstract
A magnetic transfer method includes a conjoined body formation step of stacking a transfer master storing transfer information on a transfer receiving body. Air between contact surfaces of the transfer master and transfer receiving body is pushed out in the direction of a non-pressurized area by pressurizing the stacked transfer master and transfer receiving body, to form the conjoined body. The method further includes a transfer step of, by bringing a magnetic field generating module close to the conjoined body, and applying a magnetic field, carrying out a magnetic transfer of the transfer information from the transfer master to the transfer receiving body. A surface roughness of smooth portions of the transfer master in which no transfer information is formed, and the surface roughness of the transfer receiving body, is 1 nm or less.
