Abstract

A bobbin has a winding core and multiple partitioning walls, so that multiple winding areas are formed in an axial direction. A groove is formed in each of the partitioning walls, so that a wire rod strides over the partitioning wall bypassing through the groove when a winding process for one of the winding areas is finished and a winding process for a neighboring winding area will be started. The groove has a first and a second guide wall surfaces, which are opposed to each other in a circumferential direction. Each of the first and the second guide wall surfaces is inclined in the axial direction such that each of the first and the second guide wall surfaces comes closer to a circumferential winding-end side in the axial direction to a stride-end side.
