Provided is a therapeutic electromagnetic stimulation device applying a magnetic field to an object person. The device includes a magnetic field generating means, a magnetic field detecting means, and a data generating means configured to generate custom data pairs for an individual object person. The data generating means is configured to generate the custom data pairs using: a result of detection of intensities in a state in which the magnetic field generating means are disposed respectively at a plurality of sampling spots near a specific site of the object person, and a plurality of parent data pairs each including (a) at least information of a three-dimensional position of the magnetic field generating means pairing with (b) information of the intensities of the corresponding components of the magnetic field at a position having at least the information of the three-dimensional position, and the information (a) and (b) is previously recorded.
