SENSOR

To provide a sensor that, even when a housing is configured in a divided manner, prevents an end of a shield film from being easily turned up, and is excellent in manufacturability and noise resistance.SOLUTION: A sensor 1 comprises: a receptacle 9 that can be connected to an external plug P; a second housing 3 that accommodates at least part of the receptacle 9; a main substrate 5 that has an electronic component 53 used for sensing mounted thereon; a shield film 6 that covers at least part of the main substrate 5, and blocks at least one of electromagnetic waves emitted from the main substrate 5 or electromagnetic waves to enter the main substrate 5 from the outside; a first housing 2 that accommodates at least part of the main substrate 5 and at least part of the shield film 6; a flexible substrate 8 that connects the main substrate 5 and the receptacle 9 with each other; and a protective member 10 that is in contact with an end 62 of the shield film 6 facing the flexible substrate 8 from the opposite side of the main substrate 5.SELECTED DRAWING: Figure 1 【課題】筐体を分割して構成してもシールドフィルムの端部が捲れにくい、製造性とノイズ耐性とに優れたセンサを提供する。【解決手段】センサ１は、外部のプラグＰに接続可能なレセプタクル９と、レセプタクル９の少なくとも一部が収容された第２筐体３と、センシングに用いる電子部品５３が実装された主基板５と、主基板５の少なくとも一部を覆い、該主基板５から発せられた電磁波及び外部から主基板５に侵入しようとする電磁波の少なくとも一方を遮蔽するシールドフィルム６と、主基板５の少なくとも一部及びシールドフィルム６の少なくとも一部が収容された第１筐体２と、主基板５及びレセプタクル９を接続するフレキシブル基板８と、フレキシブル基板８に面したシールドフィルム６の端部６２に対して主基板５とは反対側から当接する保護部材１０と、を備えている。【選択図】図１
