摘要： To provide an inexpensive hydrogen storage tank while the safety is ensured. A hydrogen storage tank 10 includes a liner layer 12 to store hydrogen and a carbon fiber reinforced plastic layer 14 disposed outside the liner layer 12. The liner layer 12 is formed from a low-alloy steel, and the carbon fiber forming the carbon fiber reinforced plastic layer 14 is a pitch based carbon fiber.
