A soft magnetic resin composition includes a solid content containing flat soft magnetic particles and a resin component, and a dispersion medium. Furthermore, a viscosity (A) at a shear rate of 38.1 s-1 is 300 mPa·s or more. Furthermore, a ratio (A / C) of the viscosity (A) at a shear rate of 38.1 s-1 with respect to a viscosity (C) at a shear rate of 191.5 s-1 is 1.7 or more.

The present invention provides a magnetic paste and the like, which has low viscosity even when containing a magnetic powder, and which can provide a cured product having excellent mechanical strength. The present invention provides a magnetic paste, which contains (A) a magnetic powder, (B) an epoxy resin, (C) a dispersant, and (D) a curing agent, wherein the (C) component has a polyester skeleton represented by General Formula (1) below. In General Formula (1), R each independently represents a divalent hydrocarbon group having 2 to 10 carbon atoms, and n represents an integer of 2 to 1000.

There is provided a magnetic composite including a ferrite layer and having excellent heat resistance, the ferrite layer being dense, having a relatively large film thickness, having an excellent effect of reducing magnetic loss at a high frequency, and having excellent adhesion. The magnetic composite includes a non-metallic inorganic base material and a ferrite layer provided on a surface of the non-metallic inorganic base material. The non-metallic inorganic base material has a thickness (dM) of 2.0 µm or more. In addition, the ferrite layer has a thickness (dF) of 2.0 µm or more and 50.0 µm or less, and contains spinel-type ferrite as a principal component. Further, a content of α-Fe2O3 in the ferrite layer is 3.0 mass% or more and 25.0 mass% or less.
