Claims

[Claims for Utility Model Registration] (1) An insulating base having a pair of plug terminals fixed to its tip portion connected to the cord via a noise filter element, and an annular core housing body housing the annular core of the noise filter element. and an engaging leg that engages the bottom of the annular core accommodating body with the rear end of the insulating base, and an engaging leg that is wound around the outer periphery of the annular core accommodating body and connected between the cord and the pair of plug terminals. a pair of windings, and a plug body integrally molded from the base of the pair of plug terminals to the cord, and the annular core accommodating body has a configuration that can be separated from and integrated with the engagement leg. A plug with a built-in noise filter element. (2) The noise filter built-in plug according to claim 1, wherein the annular core is arranged so that its axis is in the same direction as the axes of the cord and the plug terminal.
