To provide a method of manufacturing a label of a transparent film base material which makes reading by the light emitted by irradiation with IR rays possible and is capable of maintaining the hiding properties of printed information.

A silver color ink layer is formed in the prescribed region of the transparent film base material to be subjected to image printing with a visually unrecognizable ink and a white ink layer is formed on the silver color ink layer, then the transparent film base material is subjected to laminating, by which a transparent film layer covering the white ink layer is formed and the image printing layer is formed in the prescribed region of the transparent film base material from above the transparent film layer.
