An ion exchanger includes a sheet-shaped positive ion exchangerin which binder particlesand positive ionic exchange resin particlesare mixed with each other, and a sheet-shaped porous negative ion exchangerin which binder particlesand negative ionic exchange resin particlesare mixed with each other, the positive ion exchangerand the negative ion exchangerare bonded to each other to form an interface, and capacity of the negative ion exchangeris greater than that of the positive ion exchanger. Therefore, the porous ion exchangeris formed and absorbing ability of ion is increased, capacity of the negative ion exchangeris made greater than that of the positive ion exchanger, regenerating ability of the ion exchanger with respect to absorbing ability of ion can be secured, and ion absorption and regeneration processing is carried out efficiently.

Ion exchanger, water treatment device provided with same, and hot water supply device

Disclosed is a vacuum heat insulating material. Also disclosed is a heat insulating box using the vacuum heat insulating material. The vacuum heat insulating material includes a core member and envelope members having gas-barrier properties and including heat-seal layers. The envelope members are opposed to each other in such a manner that the core member is disposed between the heat-seal layers. The envelope members are entirely heated to a temperature at which the heat-seal layers are melted, and the heat-seal layers are heat sealed to each other by applying uniform pressure to the entire envelope members from outside to inside the envelope members.
