Abstract
An object of the present invention is to provide a method of evaluating wettability at lower cost than existing methods. According to a preferred aspect of the present invention, a wettability evaluation device includes a flow path into which a first medium and a second medium are introduced, a measuring instrument that measures a current value of a current flowing through the flow path when the first medium and the second medium are introduced, and a control unit that evaluates wettability of an inner wall surface of the flow path based on the current value.
