A magnetic structure is provided with an alumina layer formed between a ceramic substrate and a soft magnetic layer. The alumina layer has a formative energy of oxide lower than that of the soft magnetic layer to protect diffusion of oxygen to the soft magnetic layer, when the soft magnetic layer is heated to be formed. Further, a bonding glass layer is positioned between the ceramic substrate and the alumina layer, and another ceramic substrate is formed on the soft magnetic layer. <IMAGE> |
