<p>PROBLEM TO BE SOLVED: To solve the problem in which: in a liquid device, if an absorption member is coated with a barrier member such as a protective coating film, when the absorption member absorbs liquid and expands, pressure is easily applied to the absorption member due to the presence of the barrier member, which causes the backflow of the liquid absorbed by the absorption member to a channel, and thereby impairing the performance of the liquid device.SOLUTION: A liquid device 10 includes an absorption member 14 that contains a liquid-absorbing polymer absorbing liquids, and a lyophilic polymer having lyophilicity to liquids. This suppresses the backflow of a liquid absorbed by the absorption member to a channel member, and thereby providing the effect of improving the performance of the liquid device.</p> |
