A liquid charging nozzle plate (10) comprising a plate body provided with a plurality of through holes (11). This liquid charging nozzle plate (10) is used by fixing the same to a lower end opening of a liquid charging tube (67). The outflow of a liquid with which the liquid charging tube (67) is filled is prevented owing to the surface tension of the liquid in the through holes (11) of the liquid charging nozzle plate (10). On an inner circumferential surface (13) of each through hole (11), projections (15) are provided which extend in the circumferential direction so that the inner diameter of the through hole (11) decreases. Owing to the cross-sectional shape of this through hole (11), the dripping of the liquid from the through hole (11) can be prevented effectively. Even when the through holes (51) are formed cross-sectionally to an elongated slit-like shape, the dripping of a liquid therefrom can also be prevented effectively. <IMAGE> |
