Abstract:
1. A laminated electronic component comprising: a first magnetic material portion; a low-magnetic-permeability portion laminated on the first magnetic material portion, and including a plurality of laminated low-magnetic-permeability sheets; a second magnetic material portion laminated on the low-magnetic-permeability portion; at least one annular or spiral coil disposed within the low-magnetic-permeability portion; a plurality of columnar magnetic material portions disposed within the low-magnetic-permeability portion so as to extend through inside of the coil and connect the first magnetic material portion to the second magnetic material portion, the plurality of columnar magnetic material portions each including a plurality of laminated penetrating magnetic materials, the penetrating magnetic materials each penetrating the corresponding low-magnetic-permeability sheets; and a plurality of film shaped magnetic material portions each configured to intervene between two penetrating magnetic materials adjacent in a lamination direction in which the plurality of penetrating magnetic materials are laminated, the plurality of film shaped magnetic material portions each being directly in contact with the two penetrating magnetic materials.
