SENSOR UNIT

To provide a sensor unit including a plurality of pressure-sensitive sensors with a simplified wiring structure and improved connection reliability.SOLUTION: For each of laminates 13 and 14 in pressure-sensitive sensors 12A and 12B, a first sensor electrode 21 is connected to a first circuit part electrode 31 and a second sensor electrode 23 is connected to a second circuit part electrode 33. Thus, the pressure-sensitive sensors 12A and 12B are electrically connected to the circuit part 30. The first sensor electrode 21 and the second sensor electrode 23 for each of the laminates 13 and 14 are formed on a substrate 11. A negative electrode layer 16 (second electrode layer) in the laminate 13 closer to the substrate 11 is formed on a surface of a dielectric layer 17 farther from the substrate 11. A member held between the negative electrode layer 16 and the second sensor electrode 23 includes a second conductive structure that is flexible and penetrates a positive electrode layer 15 (first electrode layer) in an insulated state in a thickness direction. The negative electrode layer 16 is connected to the second sensor electrode 23 through the second conductive structure part.SELECTED DRAWING: Figure 3 【課題】複数の感圧センサを備えるセンサユニットにおいて、配線構造を簡素化しつつ接続信頼性を高める。【解決手段】感圧センサ１２Ａ，１２Ｂにおける積層体１３，１４毎の第１センサ電極２１が第１回路部電極３１に接続され、かつ第２センサ電極２３が第２回路部電極３３に接続されることで、感圧センサ１２Ａ，１２Ｂの回路部３０に対する電気的接続がなされる。積層体１３，１４毎の第１センサ電極２１及び第２センサ電極２３は基板１１上に形成され、基板１１に近い側の積層体１３における負極電極層１６（第２電極層）は、誘電層１７のうち基板１１から遠い側の面上に形成される。負極電極層１６と第２センサ電極２３とにより挟まれる部材には、柔軟性を有し、かつ正極電極層１５（第１電極層）に対し絶縁された状態で厚み方向に貫通する第２導通構造部が設けられる。負極電極層１６は第２導通構造部を介して第２センサ電極２３に接続される。【選択図】図３
