FIELD: electrical engineering.
SUBSTANCE: inductor (1A) using substrate (2) as base material comprises core fragment (3), coil fragment (4), insulating fragments (5) formed between conductors (40) of coil fragment (4), and fragments (6, 7) contact leads, which connect core fragment (3) and coil (4) part with external part. Main direction of the magnetic field, which is formed in accordance with the current flowing in coil fragment (4), goes in the direction on the plane of substrate (2). At least in fragment for coil fragment (4) both width (w) and thickness (t) of area (S1) of rectangular cross section of coil fragment (4) are set more than width (d) of insulating fragment (5).
EFFECT: technical result consists in simultaneous improvement of inductance and current density.
