A high-pressure tank comprising: a tank main body including a mouthpiece; a valve fitted to the mouthpiece; and a pipe extending from the valve in an axially inward direction of the tank main body and for ejecting a gas into the tank main body, the pipe including an ejection nozzle provided at an end of the pipe and for ejecting the gas, a first bent portion located between the ejection nozzle and the valve and extending in a direction inclined relative to an axial direction of the tank main body, and a second bent portion having the ejection nozzle and extending in a direction inclined relative to the axial direction; wherein: one of an inclination angle of the first bent portion relative to the axial direction and an inclination angle of the second bent portion relative to the axial direction is larger than 0° and not larger than 90°, and the other is not smaller than -90° and smaller than 0°, when the pipe is viewed in a direction perpendicular to the axial direction; and the pipe includes, between the first bent portion and the second bent portion, a connection portion extending in parallel with the axial direction, such that the pipe extends in the axially inward direction of the tank main body while bended at least twice in directions inclined relative to the axial direction wherein the pipe has a substantially U-shaped configuration between the first bent portion and the second bent portion, and the rigidity of the pipe is higher. a tank main body including a mouthpiece; a valve fitted to the mouthpiece; and a pipe extending from the valve in an axially inward direction of the tank main body and for ejecting a gas into the tank main body, the pipe including an ejection nozzle provided at an end of the pipe and for ejecting the gas, a first bent portion located between the ejection nozzle and the valve and extending in a direction inclined relative to an axial direction of the tank main body, and a second bent portion having the ejection nozzle and extending in a direction inclined relative to the axial direction; wherein: an ejection nozzle provided at an end of the pipe and for ejecting the gas, a first bent portion located between the ejection nozzle and the valve and extending in a direction inclined relative to an axial direction of the tank main body, and a second bent portion having the ejection nozzle and extending in a direction inclined relative to the axial direction; wherein: one of an inclination angle of the first bent portion relative to the axial direction and an inclination angle of the second bent portion relative to the axial direction is larger than 0° and not larger than 90°, and the other is not smaller than -90° and smaller than 0°, when the pipe is viewed in a direction perpendicular to the axial direction; and the pipe includes, between the first bent portion and the second bent portion, a connection portion extending in parallel with the axial direction, such that the pipe extends in the axially inward direction of the tank main body while bended at least twice in directions inclined relative to the axial direction wherein the pipe has a substantially U-shaped configuration between the first bent portion and the second bent portion, and the rigidity of the pipe is higher.
