A dispersion of tin-doped indium oxide fine particles has tin-doped indium oxide fine particles, a plasticizer for an interlayer film, an organic solvent containing alcohols as a main component, and a dispersion stabilizer, wherein under measuring conditions of a concentration of tin-doped indium oxide fine particles of 0. The program varies parameters of a point of communication, such as the location, transmission power, channel frequency, antenna height, and the like, alone or in combination, to measure, test, andor evaluate which parameter changes increase the market coverage of a target market or area. The array has more than 100000 of the droplet ejectors and extends in a direction transverse to the media feed direct between 200 mm and 330 mm.
