摘要 Provided is an electronic component that has direct current superposition characteristics such that a large inductance value can be obtained when a relatively low direct current is flowing in a coil and such that the inductance value does not drop abruptly even when a relatively high direct current is flowing in the coil. A laminate (12a) is created by lamination of magnetic layers (16a-16k). A coil (L) is built into the laminate (12a) and has a coil axis (X) that extends in the z-axis direction. The magnetic permeability of the laminate (12a) is lower than that of the magnetic layers (16a-16k), and further includes a nonmagnetic layer (17), which is laminated with the magnetic layers (16a-16k) to intersect the coil axis (X), and a high magnetic permeability part (19) that has magnetic permeability higher than that of the magnetic layers (16a-16k) and is provided to penetrate through the nonmagnetic layer (17) inside the coil (L).
