Claim:
A printing apparatus which performs printing by discharging an electroconductive liquid onto a printing medium, comprising: a liquid transporting section which includes a channel forming surface on which a liquid channel through which the liquid flows, and a discharging section communicating with the channel unit are formed, a first electrode which is arranged on the channel forming surface, and an insulating layer which is formed on a surface of the first electrode and which has a liquid repellent property higher than a liquid repellent property of the channel forming surface when no voltage is applied to the first electrode; and a transferring mechanism which transfers the liquid discharged from the discharging section of the liquid transporting section, to the printing medium, wherein a distance between the discharging section of the liquid transporting section and the transferring mechanism is less than a diameter of a liquid which is discharged at a time from the discharging section.
