Zusammenfassung:[Problem] To provide a touch sensor in which total light transmittance and haze are improved, the touch sensor is made thinner by reduction of members, and costs are lower in comparison with conventional configurations. [Solution] A touch sensor 10 is provided with a piezoelectric sensor 11 and an electrostatic capacitance sensor 12. The piezoelectric sensor 11 is provided with: a piezoelectric film 16, which is a first laminate comprising a first base material film 14 and a piezoelectric coating layer 15; a first transparent electrode 17 formed on one surface of the piezoelectric film 16; and a second transparent electrode 18 formed on the other surface of the piezoelectric film 16. The electrostatic capacitance sensor 12 is provided with: a second laminate 21 in which a third transparent electrode 20 is formed on one surface of a second base material film 19; a third laminate 24 in which a fourth transparent electrode 23 is formed on one surface of a third base material film 22; and a transparent fill layer
