The present invention relates to a tank for holding a cryogenic liquid. According to the present invention, there is provided a light and durable tank which is airtight even at cryogenic temperatures without generating cracks. The tank includes: a pressure-resistant layer having an inner shell and an outer shell; and an airtight resin layer on an inner surface of the inner shell, wherein the inner shell is comprised of a fiber-reinforced resin composite which can withstand temperatures above the melting point of the airtight resin layer, and the outer shell is comprised of another fiber-reinforced resin composite which can be cured at a temperature below the melting point of the airtight resin layer.
