ELECTROSTATIC SENSOR

To provide an electrostatic sensor capable of suppressing occurrence of incorrect detection.SOLUTION: An electrostatic sensor 100 comprises two sensor lines 112 arranged so as to be adjacent to each other and respectively covered by a surface layer 212, and a high dielectric constant material for making a dielectric constant of a first surface layer portion 212a included in the surface layer 212 higher than a dielectric constant of a second surface layer portion 212b other than the first surface layer portion 212a. The first surface layer portion 212a covers each peripheral region of the two sensor lines 112, and the second surface layer portion 212b covers regions other than each peripheral region of the two sensor lines 112.SELECTED DRAWING: Figure 6 【課題】誤検知の発生を抑えた静電センサを提供する。【解決手段】静電センサ１００は、互いに隣り合うように配置され、それぞれ表層２１２によって覆われる２つのセンサ線１１２と、表層２１２に含まれる第１表層部分２１２ａの誘電率を、第１表層部分２１２ａ以外の第２表層部分２１２ｂの誘電率よりも高くするための高誘電率材料とを備え、第１表層部分２１２ａは、２つのセンサ線１１２のそれぞれの周縁領域を覆い、第２表層部分２１２ｂは、２つのセンサ線１１２のそれぞれの周縁領域以外の領域を覆う。【選択図】図６
