A common mode choke coil array of a two-element type includes two common mode choke coil elements including at least two spiral coils and arranged side by side in a laminate body (chip member) in plan view. The spiral coils are configured so that the number of turns of the coils on the sides thereof where the coils are adjacent to each other is smaller than the number of turns of the coils on the sides thereof where the coils are distant from each other. The spiral directions of the coils arranged side by side are opposite to each other.
