Abstract
To provide ceramic electronic component capable of increasing strength of identification mark against physical impact from outside while suppressing decrease in recognition accuracy of identification mark. Ceramic electronic component includes element body containing ceramic as main material, and identification mark formed on surface of element body, at least a part of identification mark protruding from surface of element body. Element body includes first portion that surrounds identification mark and is in contact with outer edge portion of identification mark when viewed from thickness direction orthogonal to surface of element body, and second portion surrounding first portion when viewed from thickness. First portion is raised with respect to second portion.
Claims3
A ceramic electronic component comprising:
- an element body containing ceramic as a main material;
- and
- an identification mark provided on a surface of the element body, at least a part of the identification mark protruding from the surface of the element body, wherein
- the element body comprises
- a first portion surrounding the identification mark and being in contact with an outer edge portion of the identification mark when viewed from a direction orthogonal to the surface of the element body, and
- a second portion surrounding the first portion when viewed from the direction orthogonal to the surface of the element body, wherein
- the first portion is raised with respect to the second portion, wherein
- the identification mark contains ceramic as a main material, wherein
- the element body has a diffusion layer at an interface portion between the first portion and the identification mark, and wherein
- the diffusion layer is a layer in which a composition of the element body is changed by a substance constituting the identification mark diffused from the identification mark.
