Abstract
An electronic component that includes: an element body; and an insulating film covering an outer surface of the element body. The insulating film has a mix layer and a glass layer. The mix layer has a first glass and powder particles. The glass layer contains a second glass and has a smaller content percentage of the powder particles than the mix layer. The mix layer is on a side of the insulating film closer to the element body when viewed from the glass layer.

An electronic component comprising:
- an element body;
- and
- an insulating film covering an outer surface of the element body,
- wherein the insulating film includes a mix layer that contains a first glass and powder particles, and a glass layer that contains a second glass and has a smaller content percentage of the powder particles than the mix layer,
- the mix layer is on a side of the insulating film closer to the element body when viewed from the glass layer,
- wherein, in a cross-sectional view orthogonal to the outer surface of the element body, a powder particle farthest from the outer surface of the element body is designated as a specified powder particle, a first distance from the outer surface of the element body to a specified point in the specified powder particle that is farthest from the outer surface of the element body is larger than a second distance from the specified point to a surface of the glass layer,
- wherein a thermal expansion coefficient of the powder particles is larger than a thermal expansion coefficient of the glass, and
- wherein the thermal expansion coefficient of the powder particles is 0.6×10−6 to 15×10−6 (/K).
