An inner bag for bag-in-box capable of increasing an easiness in handling and convenience when a filled inner bag (1) for bag-in-box is handled without an outer box, wherein reinforcing fused parts (5, 5') formed by cutting out side films (4, 4') and fusing a front film (6) with a rear film are provided continuously or closely to tip fused parts (2, 3) on an upper side and/or a lower side of the inner bag, or a holding part is provided formed by fusing the front film (6) with the rear film through or without through the side films (4, 4') so that an unfused part (17) between the side films (4, 4') is formed at or near at least one corner part between the films and the tip fused parts (2, 3) and so that, when a hand is accessed from the side part of the inner bag (1), fingers are passed to the outside of the inner bag (1) through the unfused part (17).
