PROBLEM TO BE SOLVED: To provide a glass washing tank in which a surface state is improved, particularly the surface, through which ultrasonic waves pass, in a glass washing tank that is used for an ultrasonic cleaning device for precision equipment, semiconductor industrial components, and medical equipment, and that uses heat-resisting glass (boro-silicated glass, Pyrex(R)), laboratory glass (high silicate glass, VYCOR(R)) and also quartz glass, and to provide an ultrasonic cleaning device with the glass washing tank. SOLUTION: The glass washing tank is used for the ultrasonic cleaning device, and has a bottom wall, front/rear and left/right sidewalls, and wherein an upper part is opened. The inner and outer faces of at least one wall of the glass washing tank are made into mirror polishing plane. Wherein, the mirror-polished plane has the square mean roughness RMS of ≤0.02 μm and a flatness of ≤0.1 mm, and an energy attenuation from the ultrasonic vibrator of the ultrasonic cleaning device is defined as ≤5%.
