To provide a film for a security sensor that is inconspicuous and hardly gives the feeling of discomfort in appearance, the security sensor, and a method for manufacturing the film for the security sensor.
The film 6 for a security sensor is used, on whose flexible transparent film 21 a detection wiring 22 composed of thin metallic wires of 20 μm or less in thickness, 40-100 μm in width, and 50% or more in the total light ray transmittance is arranged. For the detection wire 22, the wire composed of thin wires which are made by plated metals (a plated layer 22b) using physically developed metallic silver (a physical development layer 22a) as a catalysis nucleus can be used, for example. The film 6 for the security sensor can be made into the security sensor by, for example, connecting the detection wire 22 and a detection circuit capable of detecting a change in resistance of the detection wire 22. The film 6 for the security sensor can be laminated on a windowpane 2 and the like.
