摘要： An inductor array includes a body including at least three coils and external electrodes arranged on external surfaces of the body. The at least three coils are arranged to be spaced apart from each other by a predetermined distance in one direction of the body, and here, the at least three coils have the same characteristic value. A minimum distance between mutually adjacent coils among the at least three coils is changed according to the number of turns of a coil pattern included in an area formed between the centers of cores of mutually adjacent coils.
