The object of the present invention is to provide a sensor which has an advantage in reduction of the noise and for down sizing, and also which are capable to produce easily. A sensor comprising: a case member housing a resistance substrate and a mobile element which slides against said resistance substrate and formed with an aperture leading to said resistance substrate; a connector member having a connector terminal, a cover unit which is a part of a resin covering said connector terminal and covers said aperture of said case member, and a connector unit which is other part of the resin covering said connector terminal and is connected with an external terminal; and a clip resiliently contacting with said connector terminal and said resistance substrate, and electrically connecting said connector terminal and said resistance substrate.
