PURPOSE:To provide a method for producing joined ferrite by which joining is enabled at a low temp., defective joining is suppressed, yield is enhanced and the joined interface is flatly controlled. CONSTITUTION:When an Mn-Zn ferrite single crystal is joined to an Mn-Zn ferrite polycrystal to produce joined ferrite, joining is carried out using substrates of an Mn-Zn ferrite single crystal and an Mn-Zn ferrite polycrystal each having <=8mum parallelism of thickness and <=0.1mum surface roughness Ra. |
