Patent attributes
A liquid supply device has a main body having a hollow portion; a partition that divides the hollow portion into a liquid storage chamber; a reservoir chamber communicated with the atmosphere; and a through hole formed in the partition. An application material is provided in the main body and applies the liquid in the liquid storage chamber. A porous relay core supplies the liquid in the storage chamber to the application material and is inserted in the through hole to form a gap with an inner wall of same, the gap holding the liquid by capillary force. A partition extending portion extends from the partition and protrudes to the liquid storage chamber side along the relay core. The relay core is inserted to form a gap holding the liquid by capillary force.
