Coil component

A coil component comprising:

• a main body portion including
• an element body having insulating properties,
• a coil inside the element body,
• a first conductor layer electrically connected to one end side of the coil, and
• a second conductor layer electrically connected to another end side of the coil, wherein
• the main body portion has a substantially rectangular parallelepiped shape, and has
• a bottom surface for mounting,
• a top surface spaced from the bottom surface in a height direction orthogonal to the bottom surface of the main body portion,
• a pair of end surfaces spaced from each other in a first direction orthogonal to the height direction,
• a pair of side surfaces spaced from each other in a second direction orthogonal to the height direction and the first direction,
• a first ridge portion between the top surface and one of the pair of end surfaces,
• a second ridge portion between one of the pair of side surfaces and one of the pair of end surfaces, and
• a third ridge portion between the top surface and one of the pair of side surfaces,
• the first conductor layer is exposed on part of the bottom surface of the main body portion and on at least part of a first end surface of the pair of end surfaces of the main body portion,
• the second conductor layer is exposed on part of the bottom surface of the main body portion and on at least part of a second end surface of the pair of end surfaces of the main body portion,
• each of the first ridge portion, the second ridge portion, and the third ridge portion defines a curved surface that is rounded to curve in a projecting shape, and
• the first ridge portion has a radius of curvature R1 that is larger than a radius of curvature R2 of the second ridge portion and a radius of curvature R3 of the third ridge portion.
