摘要:
In a laminated coil component include coil conductors are respectively included on magnetic layers and a carbon paste is included on a magnetic layer. The coil conductors include a partial coil conductor and a partial coil conductor respectively corresponding to an outer side portion circle and an inner side portion circle defining two circles. A width of the carbon paste at least partially overlaps an interval between the outer side portion circle and the inner side portion circle defining the two circles, and extends circularly along the two circles. The carbon paste is shifted to the interval between the outer side portion circle and the inner side portion circle defining the two circles at the time of pressure-bonding the magnetic layers. The carbon paste vanishes when being calcined to define an air gap.
