Coil component

A coil component comprising:

• a bare body including 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 an 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,
• wherein
• assuming that, in the first ferrite layer, a position of a principal surface on a side nearer to the first glass layer is denoted by a first position, a position 10 μm away from the first position in a negative lamination direction is denoted by a second position, a position of a principal surface on a side opposite to the first glass layer is denoted by a third position, a position 10 μm away from the third position in a positive lamination direction is denoted by a fourth position, a region between the first position and the second position is denoted by a first inner region, a region between the third position and the fourth position is denoted by a first outer region, and a region between the second position and the fourth position is denoted by a first intermediate region, where the negative lamination direction is defined as a direction extending from the second principal surface side of the first glass layer to the first principal surface side of the first glass layer, and the positive lamination direction is defined as a direction extending from the first principal surface side of the first glass layer to the second principal surface side of the first glass layer,
• an area ratio of pores in the first inner region is greater than an area ratio of pores in the first intermediate region,
• an average crystal particle size of ferrite in the first inner region is smaller than an average crystal particle size of ferrite in the first intermediate region,
• the bare body further includes a second glass layer adjacent to the first ferrite layer on a side opposite to the first glass layer and a third glass layer adjacent to the second ferrite layer on a side opposite to the first glass layer,
• an area ratio of pores in the first outer region is greater than the area ratio of the pores in the first intermediate region, and
• an average crystal particle size of ferrite in the first outer region is smaller than the average crystal particle size of the ferrite in the first intermediate region.
