The main substrate includes a flow path, an inlet for a sample, and a gas outlet, and the inlet and the gas outlet communicate with an outside. The inlet communicates with an upstream end portion of the flow path and the gas outlet communicates with a downstream end portion of the flow path. The flow path has a shape that expands from an upstream side toward a downstream side of the flow path. The sample inlet cover member is a liquid-tight member and can be fixed to the inlet when the sample inlet cover member is in use. The gas outlet cover member is a liquid-tight and gas-permeable member and can be fixed to the gas outlet when the gas outlet cover member is in use.
