Electrostatic application apparatus and method for applying liquid

摘要

An electrostatic application apparatus 100 comprises a tubular electrode 1 forming a first flow path F1 whose inner surface is formed of an electrically conductive wall; a counter electrode 20 placed to block an extension of an axis line of the first flow path F1; a power source 30 applying a voltage between the tubular electrode 1 and the counter electrode 20, and a liquid supply unit 40 supplying a liquid to the first flow path F1. If an axial length of the first flow path F1 is L1 and an inside diameter of the first flow path F1 is D1, then L1/D1 is 35 or more, the inside diameter D1 of the first flow path is 0.5 to 2.0 mm, and the length L1 of the first flow path is 20 to 100 mm.
