Abstract
A manufacturing method for a tank is a method of manufacturing the tank by winding fibers impregnated with an epoxy resin in a plurality of layers around an outer circumference of a liner having a body part and dome parts provided at both ends of the body part. The manufacturing method includes sequentially laminating a plurality of hoop layers by hoop-winding the fibers from a side closer to an outer circumference of the body part toward a side farther from the outer circumference of the body part. When laminating the hoop layers, a temperature of end portions of the body part adjacent to the dome parts is set lower than a temperature of a remaining portion of the body part, the remaining portion being a portion of the body part other than the end portions.
