PROBLEM TO BE SOLVED: To provide a sealing bag for easily taking out piece materials. SOLUTION: A sealing bag 1 comprises a bag body 10 having an opening part 14 and a slide fastener 20 to freely open/close the opening part 14. The slide fastener 20 comprises a pair of base cloth parts 21 and 22, and teeth parts 24 and 25 continuously formed to the base cloth parts 21 and 22. The opening part 14 is closed by coupling the teeth parts 24 and 25 with each other. The base cloth parts 21 and 22 are fitted along an inner surface of the opening part 14 so that edges on the side with the teeth parts 24 and 25 provided thereon are located on the open side of the opening part 14. Therefore, when materials are taken out of the inside of the bag body 10, the piece materials can be easily removed by the scraping or the like without being hindered by the teeth parts 24 and 25 of the slide fastener 20 even if the piece materials are stuffed between the inner surface of the bag body 10 and the base cloth parts 21 and 22.
