    Abstract: A composite magnetic material includes a powder and a resin. The powder has a main component containing Fe or Fe and Co. An average minor axis length in primary particles of the powder is 100 nm or less. A point satisfying (X, Y)=(σ/Av (%), (Av-σ)) on an XY coordinate plane is present within a region (including a boundary) surrounded by three points α(24.5, 6.7), β(72.0, 1.2), and γ(24.5, 1.2), in which an average of aspect ratios in the primary particles of the powder is set to Av, and a standard deviation of the aspect ratios in the primary particles of the powder is set to σ.

    Abstract: An LC composite component includes a non-magnetic substrate, a magnetic layer with magnetism, capacitors, inductors, and core parts with magnetism. The non-magnetic substrate includes a first surface and a second surface on a side opposite to the first surface. The magnetic layer is disposed to face the first surface of the non-magnetic substrate. The inductors and the capacitors are disposed between the first surface of the non-magnetic substrate and the magnetic layer. The core parts are disposed between the first surface of the non-magnetic substrate and the magnetic layer and connected to the magnetic layer. The thickness of the core parts is 1.0 or more times the thickness of the magnetic layer in a direction perpendicular to the first surface of the non-magnetic substrate, and each of the magnetic layer and the core parts contains magnetic metal particles and resin.
