Abstract
A metal magnetic particle provided with an oxide layer on a surface of an alloy particle containing Fe and Si. The oxide layer has a first oxide layer, a second oxide layer, a third oxide layer, and a fourth oxide layer. Also, in line analysis of element content by using a scanning transmission electron microscope-energy dispersive X-ray spectroscopy, the first oxide layer is a layer where Fe content takes a local maximum value, the second oxide layer is a layer where Fe content takes a local maximum value, the third oxide layer is a layer where Si content takes a local maximum value, and the fourth oxide layer is a layer where Fe content takes a local maximum value.
