Abstract
A micro lens is provided with proper optical characteristics, such as a condensing function. Furthermore, a fabrication method of a micro lens is provided as well as, an optical device, an optical transmitter, a laser printer head, and a laser printer. The micro lens is equipped with a lens member formed by a liquid droplet ejection method, including: a base member formed on a substrate, a lens member formed on an upper surface of the above-mentioned base member to which the lens material is ejected in a plurality of dots by the liquid droplet ejection method, the upper surface of the base member having a concavity and a convexity with at least a part of the upper surface of the base member being subjected to repellant treatment.

12. A fabrication method of a micro lens having a lens member formed by a liquid droplet ejection method, comprising:
-
forming on a substrate a base member having a shape of a concavity and a convexity on a surface thereof; applying repellent treatment to at least a part of the upper surface of the base member; and ejecting a lens material in a plurality of dots by the liquid droplet ejection method to the upper surface of the base member and forming a lens member on the upper surface of the base member.
