MAGNETIC CORE PART, MAGNETIC ELEMENT, AND METHOD FOR PRODUCING MAGNETIC CORE PART |
| 摘要 |
The present invention provides a magnetic core part by which failures such as cracks do not occur even if the magnetic core part contains 90% by mass or more of an amorphous metal powder. The magnetic core part is formed by thermoset molding at least one magnetic powder selected from an amorphous metal powder alone and an amorphous metal powder coated with an insulating material, and a thermosetting binder resin. The magnetic core part contains the magnetic powder in an amount of 90% by mass or more and 99% by mass or less with respect to the total amount of the magnetic powder and the thermosetting binder resin. |
