Abstract
A method for evaluating lyophobicity of an inner wall of a fine tube having a lyophobic film formed on the inner wall includes a step of setting up a fine tube having a lyophobic film extending from an end of the inner wall of the fine tube to a predetermined position of the inner wall, in a liquid placed in a unit in such a manner that the lyophobic film is positioned uppermost and also includes a step of measuring the position of the liquid surface of the liquid that has risen in the fine tube and then stopped and then determining the position of the lower end of the lyophobic film.
