A steam-releasing pouch includes two laminated sheets forming an accommodation compartment that accommodates a content, a sealing portion that seals the two sheets to form an opening that opens part of the accommodation compartment, and a steam-releasing sealing portion formed in the sealing portion to open as pressure of the accommodation compartment increases in a state in which the opening is sealed. The steam-releasing sealing portion includes a first sealant layer having at least a first base layer that faces the accommodation compartment and a second base layer laminated with the first base layer and a second sealant layer having at least a third base layer that faces the accommodation compartment and a fourth base layer laminated with the third base layer. The first base layer and the third base layer are joined together.
