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.
