Abstract
A magnetic sheet includes an adhesive layer that includes a support formed in a band shape and an adhesive provided on at least one of a first surface or a second surface of the support, and a magnetic ribbon that is formed in a band shape using a magnetic material and is bonded to the adhesive on the adhesive layer. Width A as a dimension of the adhesive layer in a direction intersecting a longitudinal direction of the adhesive layer and width B as a dimension of the magnetic ribbon in a direction intersecting a longitudinal direction of the magnetic ribbon satisfy a relationship of 0.2 mm≤(width A−width B)≤3 mm.
