Abstract

A coil component disclose includes an element body that is transmissive to visible light, a pair of external conductors on the element body, a coil in the element body, and a pair of internal conductors connecting the coil and the pair of external conductors. The element body includes a pair of end faces, a pair of first side faces, and a pair of second side faces. A length of each of the pair of end faces in a second direction and a length of each of the pair of end faces in the a direction are equal. A surface roughness of one of the pair of second side faces is lower than a surface roughness of at least one of the pair of first side faces. A coil axis of the coil intersects the pair of first side faces.

Dependent claims

A coil component comprising:

an element body that is transmissive to visible light and includes a pair of end faces opposing each other in a first direction, a pair of first side faces opposing each other in a second direction orthogonal to the first direction, and a pair of second side faces opposing each other in a third direction orthogonal to the first direction and the second direction;
a pair of external conductors on the element body;
a coil in the element body;
and
a pair of internal conductors connecting the pair of external conductors and the coil,
wherein a length of each of the pair of end faces in the second direction and a length of each of the pair of end faces in the third direction are equal,
a surface roughness of one of the pair of second side faces is lower than a surface roughness of at least one of the pair of first side faces, and
a coil axis of the coil intersects the pair of first side faces.
