Abstract
A pour-out member or, for example, a container has a pour-out port 1a through which a viscous fluid is discharged, wherein a hydrophobic layer of fine hydrophobic inorganic particles 20 is selectively formed on an upper end surface of a base member forming the pour-out port 1a. The hydrophobic layer formed on the pour-out port 1a of the pour-out member is not removed or broken through the repetitive use, and stably exhibits a function of preventing the liquid from creeping over extended periods of time.
