Abstract

A cell unit (2) comprises: a base material (10) that defines a first surface (11) and a second surface (12) facing each other; a hole (13) that penetrates from the first surface (11) to the second surface (12); a film (21) that is disposed in the hole (13) and partitions the hole (13) into a first space (15) on the first surface (11) side and a second space (16) on the second surface (12) side; a first flow path (40) that is formed on the base material (10) and serves for introducing a first fluid into the first space (15); a second flow path (42) that is formed on the base material (10) and serves for taking out a second fluid from the second space (16); a first gasket (50) disposed on the first surface (11) and surrounding the first space (15) and the first flow path (40); and a second gasket (51) disposed on the first surface (11) and surrounding the second flow path (42) on the outside of the first gasket (50).
