<P>PROBLEM TO BE SOLVED: To provide a common mode choke coil array capable of coupling three or more coils to one another and suppressing variation in common mode impedance of the coils. Ž<P>SOLUTION: The common mode choke coil array 1 is configured by a columnar insulator 2 formed in a quadrangular prism; coil patterns 3-6 provided inside the columnar insulator 2; and external terminal electrodes 8-15 provided on end surfaces 2E and 2F of the columnar insulator 2 and connected to the coil patterns 3-6. In this case, the coil patterns 3-6 oppose side surfaces 2A-2D of the columnar insulator 2 respectively, and are disposed equally spaced in a peripheral direction so as to surround a center axis O-O of the columnar insulator 2. With this configuration, the coil patterns 3-6 can be coupled to one another and the coupling between the coil patterns 3-6 can be prevented from being prohibited by the other coil patterns 3-6.
