Abstract
A coil bobbin includes a winding, a first bobbin, and a second bobbin. The first bobbin and the second bobbin are arranged side by side so that axial directions are aligned with each other. The winding is wound in a continuous manner around the first bobbin and the second bobbin and is made to traverse from the first bobbin to the second bobbin through an inside space sandwiched between the first bobbin and the second bobbin that are arranged side by side. In addition, the winding includes a slack portion in the inside space.

A coil bobbin, comprising:
- a winding;
- and a first bobbin and a second bobbin arranged side by side so that axial directions are aligned with each other, wherein
- the winding:
- is wound in a continuous manner around the first bobbin and the second bobbin;
- made to traverse from the first bobbin to the second bobbin through an inside space sandwiched between the first bobbin and the second bobbin arranged side by side;
- and
- includes a slack portion in the inside space.
A coil bobbin comprising two bobbins, wherein
- the bobbins include
- a projecting region that extends in a circumferential direction of a winding shaft portion around which a winding is wound at one end section of the bobbins,
- the projecting region is
- provided with a recessed portion formed in a recessed shape from an outer circumferential edge of the projecting region toward the winding shaft portion of the bobbins,
- the bobbins are
- arranged side by side so that axial directions of the two bobbins are aligned with each other, and the bobbins include concave-convex engaging portions that engage with each other in a state where the recessed portions inwardly oppose each other with respect to a space sandwiched between the two bobbins.
A method of manufacturing a coil bobbin including a winding and a first bobbin and a second bobbin that respectively include a winding shaft portion around which the winding is to be wound and that are arranged side by side, the method of manufacturing a coil bobbin comprising:
- winding the winding in a continuous manner around the winding shaft portion of the first bobbin and the winding shaft portion of the second bobbin in a state where the first bobbin and the second bobbin are vertically arranged so that the respective winding shaft portions are aligned in an approximately linear shape;
- and
- folding and arranging the first bobbin and the second bobbin side by side so that a traverse portion being a length region that straddles the first bobbin and the second bobbin in the winding is positioned inside.
