1. A coil component comprising:
an element body including magnetic layers; and
a coil provided in the element body and spirally wound along a first direction,
the coil having a plurality of coil conductor layers stacked along the first direction,
the element body having a first area between the coil conductor layers adjacent to each other along the first direction and having a second area other than the first area, the second area being directly adjacent to the first area on both sides of the first area in a same one of the magnetic layers,
the first area having a pore area rate less than a pore area rate in at least a portion of the second area,
the element body having a vicinity area located in a vicinity of each of the coil conductor layers,
the second area including an out-of-vicinity area other than the first area, the out-of-vicinity area located outside the vicinity area,
the pore area rate in the first area being less than a pore area rate in the out-of-vicinity area,
a pore area rate in the vicinity area being less than the pore area rate in the out-of-vicinity area, and
the vicinity area being limited to within 20 μm or less from a surface of the coil conductor layer.
