Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a dynamic contact angle measuring device for measuring a dynamic contact angle excellently, even when a liquid sample is moved at high speed of about several meters/second or higher relative to a solid sample. SOLUTION: A measuring container 10 includes a channel 10a in which the liquid sample flows. A part of the measuring container 10 includes a transparent body, and a part of the inner surface of the measuring container 10 partitioning the channel 10a includes the solid sample. A liquid supply recovery means 20 supplied and/or recovers the liquid sample to/from the channel 10a at an optional flow rate. A photographing means 30 photographs a liquid surface shape of the liquid sample flowing in the channel 10a from a part of the transparent body of the measuring container 10.
