Disclosed is a paste for formation of a transparent electroconductive coating film, which comprises as a main component an organic indium complex having an oxygen atom coordinated directly to the indium atom, which is capable of forming an indium oxide film by sintering, such as trisacetylacetonatoindium (III). This paste provides a coating film having a low resistivity and a high transparency by screen printing and sintering, and has a good stability and a long pot life. If an organic tin compound such as tin octylate, dibutyl tin dilaurate or tetraacetylacetonatotin is incorporated as a resistivity-adjusting agent into this paste in an amount such that the Sn/(In+Sn) atomic ratio is 2 to 20%, especially good results are obtained. A cellulose derivative such as ethyl cellulose, nitrocellulose, acetyl cellulose or benzyl cellulose is advantageously incorporated as a viscosity builder into the paste.
