Official abstract text for this publication.
A coil device includes a core ( 20 ) having a columnar shaft ( 22 ), a first winding part ( 42 ) and a second winding part ( 46 ) that are wound around the shaft, and a terminal part ( 52 ) connected with ends of the first winding part and ends of the second winding part. A partition portion ( 30 ) provided on an outer peripheral surface ( 22 a ) of the shaft of the core protrudes from the outer peripheral surface toward the outer diameter direction and divides a part of the first winding part and a part of the second winding part.

1 . A coil device comprising: a core having a columnar shaft; a first winding part and a second winding part that are wound around the shaft; and a terminal part connected with ends of the first winding part and ends of the second winding part, wherein a partition portion provided on an outer peripheral surface of the shaft of the core protrudes from the outer peripheral surface toward the outer diameter direction and divides a part of the first winding part and a part of the second winding part. 2 . The coil device as set forth in claim 1 , wherein the core includes a first flange and a second flange, the first flange is connected with one end of the shaft and protrudes further toward the outer diameter direction than the outer peripheral surface, the second flange is connected with the other end of the shaft and protrudes further toward the outer diameter direction than the outer peripheral surface, and an outer diameter directional end of the partition portion is arranged closer to the outer peripheral surface of the shaft than outer diameter directional ends of the first flange and the second flange. 3 . The coil device as set forth in claim 1 , wherein at least one of another part of the first winding part and another part of the second winding part is arranged in the outer diameter direction of the partition portion. 4 . The coil device as set forth in claim 2 , wherein at least one of another part of the first winding part and another part of the second winding part is arranged in the outer diameter direction of the partition portion. 5 . The coil device as set forth in claim 1 , wherein the partition portion is part of the core. 6 . The coil device as set forth in claim 1 , wherein the partition portion is continued in the outer peripheral direction of the shaft. 7 . The coil device as set forth in claim 1 , further comprising: an exterior resin configured to coat winding portions of the first winding part and the second winding part.
