Abstract
An electrolyte measuring structure includes a housing and a sealing material. The electrolyte measuring structure being connectable to another electrolyte measuring structure via the sealing material. The housing includes a main body having a flow path therethrough and a fixing structure. The fixing structure includes a first protrusion having a first hole, a second protrusion, and a fixing recess. The sealing material includes a front surface and a back surface. The sheet region has a second hole. In a state where the sealing material is fixed, a first protrusion amount is larger than a second protrusion amount. When viewed in a cross-section passing through a central axis of the second hole in a state where the sealing material is removed from the fixing structure, a first slope defined below is smaller than a second slope.
