摘要： A tank including: a liner which is an inner shell; and a reinforcing layer covering the outer surface of the liner; wherein the reinforcing layer is formed by continuously winding resin-impregnated fiber bundles around the liner; the reinforcing layer includes a hoop layer placed in the liner side, and a helical layer; gaps are formed between adjacent bundles of the resin-impregnated fiber bundles wound in the hoop layer; there is at least one site where the resin-impregnated fiber bundles are wound without forming a gap between adjacent bundles in the helical layer; and the resin constituting the tank has a resin toughness value of not less than 1.0 MPa·m 0.5 . An inexpensive tank for which accurate arrangement of resin-impregnated fiber bundles, an apparatus for detecting gaps between resin-impregnated fiber bundles, and the like are not required; and a production method therefor; are provided.
