PROBLEM TO BE SOLVED: To provide at low cost a liquid flow path device capable of simply converting a liquid flow path to an open state from a closed state. SOLUTION: A liquid flow path device, in which a liquid flow path through which liquid flows and one or more liquid tanks 14a for storing liquid are formed on at least one side of a substrate 11 and a lid plate 13 is laminated on the fluid path forming surface of the substrate 11, has an opening means S1 for setting a part of the liquid flow path from a closed state to an open state. The opening means S1 comprises a seal plug 15 arranged at a part of the liquid flow path and plastically deformed by operation for pressing the lid plate 13 or the bottom of the liquid flow path from the outside to set the open state.
