PROBLEM TO BE SOLVED: To provide a touch panel sensor configured to effectively obscure a pattern of a sensor electrode.SOLUTION: A touch panel sensor 30 includes a protective sheet body 40, a sensor laminate 60 having sensor electrodes 61, 62 formed of a predetermined pattern, and an intermediate layer laminate 50 formed between the protective sheet body and the sensor laminate 60. The intermediate laminate 50 includes a first layer 51 arranged adjacent to the protective sheet body, and a second layer 52 arranged adjacent to the first layer 52 and located between the first layer 51 and the sensor laminate 60. A refractive index nof the first layer, a refractive index nof a second layer, and a refractive index nof a part of the protective sheet body adjacent to the first layer satisfy one of the following conditions (a) and (b): n>nand n<n(a); and n<nand n>n(b). The thickness of the first layer is 30 nm or less. |
