Various defects that occur when a water-repellent or defoaming layer is formed on a contact portion of a liquid container are reduced. A method for manufacturing a liquid container for containing a liquid includes: (a) preparing a pre-formation liquid container in which a surface layer has not been formed; (b) bringing an aqueous solution obtained by adding water to one of a defoaming agent and a water-repellent agent into contact with a surface of a contact portion with which the liquid is brought into contact, of the pre-formation liquid container; and (c) drying, after the step (b), the contact portion to form the surface layer that is formed of one of the defoaming agent and the water-repellent agent on a surface of the contact portion.
