Abstract: A liquid containing body includes a liquid containing vessel, and a casing member. The liquid containing vessel contains a liquid, and includes a supply member with a liquid supply opening that supplies the liquid to a liquid consumption apparatus. The casing member supports at least the supply member. The supply member has a cylindrical flow path section that defines the liquid supply opening. The casing member has a through hole forming section with a through hole. The cylindrical flow path section is insertable in the through hole. The casing member further has an engaging section that engages with the supply member to regulate movement of the cylindrical flow path section in an opposite direction to an insertion direction while the cylindrical flow path section is rotated with the insertion direction as an axial line in a state where the cylindrical flow path section is inserted in the through hole.
