ABSTRACT:
To provide a composite magnetic device having characteristics of two magnetic elements, being capable of reducing a manufacturing cost, and preferably enabling the respective magnetic elements to easily exhibit the same characteristics. The composite magnetic device includes: a first core member which includes an outer tube portion having a tubular shape and a partition portion partitioning an inner space (P) of the outer tube portion into two inner spaces; second core members each including a first flange portion and a second flange portion, the second core members being arranged in a state in which a magnetic gap is formed at least between the partition portion and the second flange portion, and being arranged in each of the two inner spaces (P) on each side of the partition portion; coils each arranged on a spool portion present between the first flange portion and the second flange portion; and terminal members arranged on an outer peripheral surface of the outer tube portion and electrically connected to ends of the coils.
