An indicator panel for an instrument includes a translucent resin substrate having a first face and a second face opposite to the first face, and a design film on the first face of the substrate. The design film includes a translucent portion through which a light from the second surface of the substrate is transmitted, and an opaque portion which does not transmit the light from the second face of the substrate. The design film is produced by jetting droplets of a UV hardening type colored ink to the first face of the substrate in an inkjet printing, and radiating ultraviolet rays for a time within one second from the jetting so as to harden a mass of the droplets, in which a volume of the droplets is equal to or less than 30 pl.
