The purpose of the present invention is to provide a microwave packaging bag enabling excellent discharge of steam even when the content therein has a high boiling point. This microwave packaging bag includes: a main body that is formed into a bag shape by thermally fusing together the peripheral edges of at least one film; and a flap (18) that is provided at a position biased outward from the center of the main body in a first direction while spanning the width of the main body in a second direction, and formed into a steepled configuration by a portion of the at least one film. A steam-releasing seal part (18e) is provided to the flap (18) and also provided so as to protrude toward the center of the main body. The steam-releasing seal part (18e) is formed into an irregular V-shaped configuration constituted from a first V-shaped part (30) that is continuous from a band-like seal part (18f) and missing a tip part thereof, and a second V-shaped part (40) that is continuous at a different angle from both inclined sides (31) of the first V-shaped part (30). |
