摘要： A coil electric conductor (1) has an insulating substrate (2), a first conductive layer (3), and a second conductive layer (5). The first conductive layer (3) is formed at a depression (4) provided on a face of the insulating substrate (2). The second conductive layer (5) is formed on the first conductive layer (3) with the first conductive layer (3) interposed between the second conductive layer (5) and the insulating substrate (2). This construction realizes a coil electric conductor having a highly precisely uniformized cross-sectional shape.

摘要： An oxide magnetic material provided by the present invention contains, as main components, 61 to 67 mol% of Fe₂O₃; 3 to 36 mol% of MnO; and 30 mol% or less of ZnO, and further contains, as sub-components, 0.05 to 0.5 wt% of CaO; and 0.005 to 0.2 wt% of SiO₂. Such materials can further contain one or more kinds of oxides selected from the group consisting of ZrO₂, HfO₂, Ta₂O₅, Cr₂O₃, MoO₃, WO₃, Al₂O₃, Ga₂O₃, In₂O₃, GeO₂, SnO₂, Sb₂O₃ and Bi₂O₃. Such magnetic materials of the present invention have the advantages of having an extremely low magnetic loss even when used in the high frequency band and having a minimum magnetic loss at a temperature sufficiently higher than room temperature. Moreover, a switching power supply having a switching frequency of 300 kHz to 5 MHz is provided by using such magnetic materials as a magnetic core.
