To provide a pressure sensor sheet which solves the problem that conventional pressure sensor sheets are inadequate as test devices for measuring performance and the like, as they are not capable of measuring a ground contact pressure distribution of shear force applied from an oblique angle, and thus not capable of deriving a true state of contact with a ground surface.SOLUTION: A pressure sensor sheet disclosed herein has an insulating layer with gradation to reduce internal stress deformation that causes noise. Such an arrangement enhances detection sensitivity and results in more accurate measurement of shear force.SELECTED DRAWING: Figure 1 【課題】 従来の圧力センサーシートでは、斜め方向から加わるせん断力の接地圧分布を測定することはできない。したがって、接地面との真の接地状態を測定することになっておらず、性能等を測定する試験装置としては不十分であるという問題があった。本発明は、その問題を解決できる圧力センサーシートを提供する。【解決手段】 絶縁層に階調を設けることで、ノイズとなる内部応力歪みを減少させる。それにより検出感度が向上し、結果的にせん断力を正確に計測できる。【選択図】図１
