摘要：

Provided is a water-disintegrable sheet in which an aqueous medicine is impregnated into multiple plies of a base sheet that contains pulp and carboxymethyl cellulose as a soluble binder and that can be substantially dispersed in water, and the sheet has protruding embossments formed over the entirety of at least the front surface and/or the rear surface of the sheet. The basis weight of the multiple plies is 30-150gsm. Four sheets of the water-disintegrable sheet are stacked and placed on a prescribed tile which is horizontally maintained, a 1kg weight is set on top of the water-disintegrable sheets, a load is applied in the horizontal direction from one end of the water-disintegrable sheets, and the load when the water-disintegrable sheets are moved 60mm in 6 seconds is measured. Frictional force measurement, for measuring the maximum load as frictional force at such time when the load is measured, is carried out five times for each of the MD direction and the CD direction, the average of measurement values for each of a prescribed number of measurements in the respective directions is calculated, and the present invention is configured so that each of the average values is at least 4.5N.
