PROBLEM TO BE SOLVED: To provide a transformer in which the wiring work is easy, wiring accuracy is superior, and variation in the characteristic is less, and to provide a bobbin suitable for the transformer.SOLUTION: A bobbin 6 has a first end lock part 20 to which a first end 8a of a wire 8 for the primary winding can be locked, and a second end lock part 40 to which the other second end 8b of the wire 8 for the primary winding can be locked. The first end lock part 20 has a first locking support 22 projecting from the outer periphery of the bobbin 6 in the X axis direction, a first insertion protrusion 26 forming a first insertion gap 24 into which the wire 8 for the primary winding can be inserted from the Z axis direction, and a first wire end movement limitation part 28 for limiting the motion of the first end 8a of the wire 8 for the primary winding passed through the first insertion gap 24 in the Z axis direction, and the motion of the first end 8a of the wire 8 for the primary winding in the direction winding around the outer periphery of the bobbin 6. |
