A method for manufacturing a high-pressure tank includes: a placement process of disposing an intermediate body (200) including a liner (102) and a fiber bundle wound around the liner (102) in a cavity (40) of a mold (11); and an impregnation process of increasing the pressure of the molten resin injected into the cavity (40) to impregnate the fiber bundle with the molten resin in the cavity (40), wherein the impregnation process includes a pressure raising process which increases the internal pressure of the intermediate body (200) when the pressure of the molten resin is increased. 고압 탱크의 제조 방법은, 금형(11)의 캐비티(40) 내에, 라이너(102)와 상기 라이너(102)에 권회되어 있는 섬유 다발을 포함하는 중간체(200)를 배치하는 배치 공정과, 상기 캐비티(40)에 주입되는 용융 수지를 승압하여, 상기 캐비티(40) 내의 상기 용융 수지를, 상기 섬유 다발에 함침시키는 함침 공정을 구비하고, 상기 함침 공정은, 상기 용융 수지의 승압 시에, 상기 중간체(200)의 내압을 상승시키는 승압 공정을 포함한다.
