Abstract
A first ceramic layer of a composite laminate included in a common mode choke coil is formed from a sintered body of a glass ceramic material. The glass ceramic material contains 40 to 90 percent by weight of a glass which contains 0.5 to 5 percent by weight of KO, 0 to 5 percent by weight of AlO, 10 to 25 percent by weight of BO, and 70 to 85 percent by weight of SiO; and 10 to 60 percent by weight of a filler containing alumina and quartz, and the content of the alumina contained in the filler is 1 to 10 percent by weight of the total amount of the glass and the filler.
