ABSTRACT:
According to the present invention, a hybrid magnetic substrate is provided, which includes: a magnetic substrate; and a holding substrate directly bonded to the magnetic substrate through at least one of a hydrogen bond and a covalent bond. Furthermore, a method for producing a hybrid magnetic substrate having the magnetic substrate and the holding substrate is provided, which includes the steps of: cleaning a surface of the magnetic substrate to be bonded and a surface of the holding substrate to be bonded; allowing the cleaned surfaces to be subjected to a hydrophilic treatment; and attaching the surfaces, which are subjected to the hydrophilic treatment, to each other to directly bond the magnetic substrate to the holding substrate.
