Abstract
A coil component includes a porous ceramic portion having pores, a coil portion embedded in the porous ceramic portion, and outer electrodes which are provided on an outer surface of the porous ceramic portion and electrically connected to the coil portion. The porous ceramic portion has a porosity of 10% by volume or more and 90% by volume or less (i.e., from 10% by volume to 90% by volume), and the pores are filled with a cured product of a resin composition containing a cycloaliphatic epoxy resin and an acid anhydride-based curing agent.
