Abstract
A flow channel module comprises a flow channel plate, a flow channel connection block, and a pressing mechanism. The flow channel plate is provided with a main body and a protrusion section protruding in the circumferential direction from the peripheral edge of the main body, the protrusion section having a port communicating with an inner flow channel. The flow channel connection block is provided with a concave section for being engaged with the protrusion section and having inside a port facing surface for facing the port, and an outer flow channel connection section that is connected to the port facing surface by a flow channel. The pressing mechanism is configured to press the protrusion section inserted in the concave section and the port facing surface against each other so that the flow channel and the port are connected while maintaining air tightness or liquid tightness.
