A chip inductor has electrode layers, insulating layers disposed on the electrode layers, and an uppermost insulating layer all disposed on a ceramic board. An inorganic pigment such as a Co oxide or an Al oxide is added to the insulating layer at a concentration of from about 2% to about 20% by weight. Break grooves are formed in the form of a lattice on the insulating layer by a laser beam irradiation, and the board is divided along the grooves. By adding the inorganic pigment, the break grooves are effectively formed, and the mother board is divided accurately along the break grooves, such that a chip inductor having an increased L value and an increased Q value is produced.
