Abstract
A coil unit may include coil holding member configured to hold a coil; and a coil held by the coil holding member and formed by a conducting wire in a wound state. A direction perpendicular to a length direction of the conducting wire is a thickness direction of the coil. The coil holding member may include an abutment surface configured to abut against one end surface in the thickness direction of the coil, a convex unit protruding from the abutment surface and around which the conducting wire is wound, and a coil pressing unit extending from a front end surface of the convex unit and configured to press the other end surface in the thickness direction of the coil.

A coil unit, comprising:
- a coil holding member configured to hold a coil;
- and
- a coil held by the coil holding member and formed by a conducting wire in a wound state;
- wherein a direction perpendicular to a length direction of the conducting wire is a thickness direction of the coil;
- and
- the coil holding member comprises:
- an abutment surface configured to abut against one end surface in the thickness direction of the coil,
- a convex unit protruding from the abutment surface and around which the conducting wire is wound, and
- a coil pressing unit extending from a front end surface of the convex unit and configured to press the other end surface in the thickness direction of the coil.
A method of manufacturing a coil unit comprising a coil holding member configured to hold a coil;
- and a coil held by the coil holding member and formed by a conducting wire in a wound state;
- wherein a direction perpendicular to a length direction of the conducting wire is a thickness direction of the coil;
- and the coil holding member comprises an abutment surface configured to abut against one end surface in the thickness direction of the coil, a convex unit protruding from the abutment surface and around which the conducting wire is wound, and a coil pressing unit extending from a front end surface of the convex unit and configured to press the other end surface in the thickness direction of the coil, the method comprising:
- forming a protrusion in the convex unit of the coil holding member, and after attaching the coil to the convex unit, forming the coil pressing unit by deforming the protrusion.
