A diffuse reflection material, a diffuse reflection layer, a wavelength conversion device, and a light source system are disclosed. The diffuse reflection material includes white scattering particles and an adhesive agent, where the whiteness of the white scattering particles is greater than 85, and the white scattering particles contain high reflection scattering particles with a whiteness of greater than 90, high refraction scattering particles with a refractive index of greater than or equal to 2.0, and high thermal conductivity scattering particles, where the high thermal conductivity scattering particles are boron nitrite and/or aluminum nitride particles, and the particle shape of the high thermal conductivity scattering particles is rod-like or flat.

A powder magnetic core having excellent specific resistance or strength. The powder magnetic core has soft magnetic particles, first coating layers that coat the surfaces of the soft magnetic particles and include aluminum nitride, and second coating layers that coat at least a part of the surfaces of the first coating layers and include a low-melting-point glass having a softening point lower than an annealing temperature for the soft magnetic particles. The first coating layers including aluminum nitride are excellent in the wettability to the low-melting-point glass which constitutes the second coating layers and suppress diffusion of constitutional elements between the soft magnetic particles and the low-melting-point glass of the second coating layers. The powder magnetic core can stably exhibit a higher specific resistance and higher strength than the prior art owing to such a synergistic action of the first coating layers and second coating layers.
