device for structure formation and mechanisms for structure formation of a elektroleitender liquid on a printable medium

摘要

A pattern forming apparatus (1) which forms a pattern of an electroconductive liquid on a printing medium (5) includes a pattern forming substrate (10) having an insulating substrate (11), a plurality of electrodes (13) arranged on the insulating substrate, and an insulating layer (15) which covers the electrodes, an electric potential controller (64) which selectively applies an electric potential to the electrodes, and a transferring mechanism (30) which transfers the pattern by bringing the electroconductive liquid (3) formed as a predetermined pattern on the insulating layer, in contact with the printing medium. Accordingly, it is possible to form a fine pattern at a low cost.
