Abstract
A coil component includes a bare body including, in a lamination direction, a first glass layer, a first ferrite layer adjacent to one principal surface side of the first glass layer, and a second ferrite layer adjacent to the other principal surface side of the first glass layer, a coil inside the first glass layer, and outer electrodes on surfaces of the bare body and electrically connected to the coil. Assuming that a region between first and second positions is a first inner region, a region between third and fourth positions is a first outer region, and a region between the second and fourth positions is a first intermediate region, an area rate of pores in the first inner region is greater than in the first intermediate region, and an average crystal particle size of ferrite in the first inner region is smaller than in the first intermediate region.
