Abstract
Magnetic pastes which include a magnetic powder (A) and a binder resin (B), in which, in the particle diameter distribution of the component (A), the 10% particle diameter (D) is 0.2 μm or larger and 2.0 μm or smaller, the 50% particle diameter (D) is 2.0 μm or larger and 4.3 μm or smaller, and the 90% particle diameter (D) is 4.3 μm or larger and 8.5 μm or smaller, suppress the magnetic powder from being unevenly distributed, and are useful for forming inductor elements and circuit boards.
