The present invention relates to a liquid conveying device and the like having a structure which liquid conveying can be performed to a sufficient height, while requiring no energy for liquid conveying and having a high degree of freedom of arrangement. The liquid conveying device 1 comprises a liquid conveying pipe 10, and a filter 20. The liquid conveying pipe 10 includes a minute tube having a through hole with a substantially uniform inner diameter over the whole longitudinal length thereof. The filter 20 has a mesh size smaller than the inner diameter of the through hole of the minute tube. When supplied to a first end of the liquid conveying pipe 10, a liquid passed through pores of the filter 20 is guided from the first end to a second end of the liquid conveying pipe 10 by a capillary action in the through hole.
