PROBLEM TO BE SOLVED: To provide a capacitance sensor which allows for accurate detection of grasp, when built in a rim having a rim cross section including a portion of different curvature.SOLUTION: A capacitance sensor 20 includes a flexible insulator film 40, multiple electrodes 50A-50L provided in the rim cross section circumferential direction Q at intervals, and electrode wirings 80A-80L extending, respectively, from the electrodes 50A-50L. The multiple electrodes 50A-50L include multiple electrode sets, each constituted of a central electrode, a first side electrode adjacent to the central electrode, and a second side electrode adjacent to the central electrode. The electrode intervals W, Wbetween the central electrodes 50I, 50D and side electrodes 50J, 50E of the electrode sets S, Splaced at the parts of the rim cross section having large curvatures C, Care shorter than the electrode interval Wbetween the central electrode 50F and side electrode 50G of an electrode set Splaced at a part of the rim cross section having a small curvature C.SELECTED DRAWING: Figure 10

    【課題】曲率の異なる部分を含むリム断面を有するリムに組み込まれた際に正確に把持を検出することを可能とする静電容量センサを提供する。【解決手段】静電容量センサ20は、可撓性を有する絶縁フィルム40と、リム断面周方向Qに沿って間隔をあけて設けられる複数の電極50A〜50Lと、電極50A〜50Lのそれぞれから延びる電極配線80A〜80Lとを備える。複数の電極50A〜50Lは、中央電極と、中央電極に隣接する第1の側方電極と、中央電極に隣接する第2の側方電極とにより構成された電極セットを複数含む。リム断面の大きな曲率C1,C3を有する部分に配置された電極セットS1,S2の中央電極50I,50Dと側方電極50J,50Eとの間の電極間隔W1,W2は、リム断面の小さな曲率C2を有する部分に配置された電極セットS3の中央電極50Fと側方電極50Gとの間の電極間隔W3よりも短い。【選択図】図10
