Valve device

A valve device comprising:

• a flow path member having a flow path;
• a plurality of solenoid valves configured to open and close;
• and
• a support member configured to support the plurality of solenoid valves from below in an up-down direction and be stacked with the flow path member in the up-down direction, wherein
• when a part located at an uppermost position in the up-down direction of each of the solenoid valves is defined as an uppermost portion,
• the flow path is spaced from the uppermost portions of the plurality of solenoid valves in a direction perpendicular to the up-down direction,
• the flow path extends in a direction intersecting the up-down direction,
• a width of the flow path is smaller than a depth of the flow path,
• the flow path includes a main flow path and a plurality of sub flow paths that are connected to the main flow path and separately opened and closed by the plurality of solenoid valves,
• when the direction perpendicular to the up-down direction is defined as a first direction, and a direction perpendicular to both the up-down direction and the first direction is defined as a second direction,
• the plurality of sub flow paths each include a first part extending in the first direction, and
• the first parts of the plurality of sub flow paths are alternately aligned with the plurality of solenoid valves in the second direction.
