There is provided a container that makes it possible to suppress intrusion of bacteria from the tip of a pleat part into the inside of the container. The container includes: a main body that includes a body part defining a containing portion and a flange part extending outward from an upper portion of the body part; and a lid that is joined to the flange part of the main body via an outer edge seal portion so as to cover the containing portion, the lid being formed by a lid member folded back at a fold-back portion such that portions of the lid member overlap each other. The lid has: a pleat part that includes the portions of the lid member overlapping each other and that extends from an edge of one side to an edge of the other side of the lid in a first direction; and a first lid part and a second lid part that are formed by the lid member and that are arranged on opposite sides of the pleat part. The pleat part includes: a pleat seal portion in which inner surfaces of the portions of the lid member are joined together and that extends from the edge of the one side to the edge of the other side of the lid in the first direction; and a steam passing portion that includes a through hole or a cutout formed in the pleat seal portion. Seal strength of the pleat seal portion is lower than that of the outer edge seal portion.
