Health device flow path formation member, health device flow path formation unit, and health device

A health device flow path formation member, comprising:

• a flow path configured to supply fluid to a target supply member;
• a first opening portion located at a first end of the flow path;
• a second opening portion located at a second end of the flow path;
• a connection path connecting the first opening portion and the second opening portion;
• a plate-like member comprising the connection path;
• and
• a first adhesive layer comprising at least the first opening portion of the first opening portion and the second opening portion, the first adhesive layer adhering the plate-like member to a fluid supply source with the first opening portion communicating with a fluid path of the fluid supply source;
• wherein
• when viewed in a first direction in which the first adhesive layer and the plate-like member overlap, the first opening portion is disposed inward a distance from a profile line of a projection of the connection path in the first direction, forming a first protrusion portion in the first adhesive layer that protrudes inward from the profile line;
• the connection path comprises a main path portion provided inside the plate-like member, a first auxiliary path portion connecting the first opening portion and the main path portion, and a second auxiliary path portion connecting the second opening portion and the main path portion;
• when viewed in the first direction, the first auxiliary path portion is disposed inward from the main path portion, forming a first projection portion in the plate-like member that defines the first auxiliary path portion and projects inward from the main path portion;
• and
• the first protrusion portion is supported by the first projection portion.
