Claim Text:
1. A method for manufacturing a liquid container in which a negative pressure generating member is contained in a first recessed portion separated from a second recessed portion by a partition wall with a communication portion formed therein, the method comprising: a compression step of pressing, before the negative pressure generating member is placed in the first recessed portion, a plurality of outer surfaces of the negative pressure generating member so that the negative pressure generating member becomes smaller than an opening of the first recessed portion, the plurality of outer surfaces of the negative pressure generating member including a first outer surface which is pressed by a first compression member and which is to contact a surface of the partition wall positioned in the first recessed portion and a second outer surface which is pressed by a second compression member and which is to contact an inner surface of the first recessed portion lying opposite the partition wall; and a placing step of placing the negative pressure generating member in the first recessed portion while releasing the pressure exerted on the first outer surface by the first compression member and while maintaining the pressure exerted on the second outer surface by the second compression member so that the negative pressure generating member is positionally biased toward the partition wall, and after the negative pressure generating member is placed in the first recessed portion, releasing the pressure exerted on the second outer surface by the second compression member.
