摘要： PROBLEM TO BE SOLVED: To provide a liquid container and its manufacturing method capable of keeping a degassing effect by sucking the gas in a liquid containing chamber to a degassing chamber side by a pressure difference even after it is unsealed from a decompression package. SOLUTION: The liquid container includes a case 10 in which at least one liquid containing chamber 370, 390, 430 communicated with the outer air is formed and includes an opening sealing film which seals an opening surface of the case 10. The liquid container is packaged in the decompression package until it is used by a consumer and opened upon usage. In the liquid container, sealed space which is disposed adjacent to the at least one liquid containing chamber 370, 390, 430, is not filled with liquid, and is not communicated with the outer air even after unsealing of the decompression package serves as decompression space, thus at least one degassing chamber 501 which sucks the gas in the at least one liquid containing chamber 370, 390, 430 by the pressure difference is provided.
