A liquid tank and a tubular structure for the liquid tank that allow liquid contained in the tank to be sucked out until the last drop even when the tank is tilted to any angle. The tubular structure(40) has tube paths (41) extending from a specific position (41A) inside a tank body (30) to vertices, sides, or faces of the tank body (30). The forward ends of the pipe paths (41) are in contact with the vertices, the sides, or the faces of the tank body (30) and have liquid inlet openings (41B). Because the inlet openings (41B) are located only at the forward ends of the tube paths (41), the flow of the liquid in the tank body (30) has specific directionality in which the liquid enters a tube path (41) only from the corresponding inlet opening (41B) and sucked to the outside after being conveyed to the specific position (41A). Inside the tubular structure (40) is provided an inner structure body (45), such as a porous body, having cavities for allowing the liquid to pass through them. The cavities have an avera
