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; wherein said clip comprises a fulcrum and two leg units consisting of a first leg unit and a second leg unit extending to two directions from said fulcrum and said clip has a cross sectional shape of roughly a V shape or U shape, said clip is engaged with an end unit of said resistance substrate in a status that said resistance substrate is sandwiched between said first leg unit and said second leg unit, a housing depression is formed in said connector member at a position opposing said resistance substrate, said housing depression comprises a first lateral wall contacting with a first external face which is an external face of said first leg unit and a second lateral wall contacting with a second external face which is an external face of said second leg unit, and said housing depression houses said clip in a status that said clip is sandwiched between said first lateral wall and said second lateral wall, and a part of said connector terminal is exposed from the resin covering said connector terminal to form at least one of said first lateral wall and said second lateral wall. 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; wherein said clip comprises a fulcrum and two leg units consisting of a first leg unit and a second leg unit extending to two directions from said fulcrum and said clip has a cross sectional shape of roughly a V shape or U shape, said clip is engaged with an end unit of said resistance substrate in a status that said resistance substrate is sandwiched between said first leg unit and said second leg unit, a housing depression is formed in said connector member at a position opposing said resistance substrate, said housing depression comprises a first lateral wall contacting with a first external face which is an external face of said first leg unit and a second lateral wall contacting with a second external face which is an external face of said second leg unit, and said housing depression houses said clip in a status that said clip is sandwiched between said first lateral wall and said second lateral wall, and a part of said connector terminal is exposed from the resin covering said connector terminal to form at least one of said first lateral wall and said second lateral wall.
