Summary:PROBLEM TO BE SOLVED: To provide a coil component which can enhance DC superposition characteristics while maintaining good inductance characteristics. SOLUTION: The coil component C1 comprises a core portion 12, a core 2 having a pair of flange portions 14 and 15 arranged at the opposite ends of the core portion 12, a winding 4 wound in contact with the core portion 12 and arranged in a region between the pair of flange portions 14 and 15, a first coated part 8 composed of cured resin containing a magnetic material and arranged in a region between the pair of flange portions 14 and 15, and a second coated part 10 composed of a nonmagnetic material and interposed between the pair of flange portions 14, 15 and the first coated part 8.
