The present invention superimposes the liquid permeable surface sheet and the liquid impermeable back sheet and fusions (adheses) the edges, and incorporates a superabsorbent polymer (core) between the liquid permeable surface sheet and the liquid impermeable back sheet to absorb water. Form a pad, but install (fusion and glue) the split type leakage blocking sheet on both sides (front and rear) in the longitudinal direction from the upper surface of the absorbent pad, or install the integrated leakage blocking sheet having inflow holes formed on the upper surface of the absorbent pad. It is a leak-proof disposable absorbent pad, characterized in that the adhesive). The present invention installs (fusions and glues) an integrated leakage blocking sheet having an inlet hole formed on the upper surface (surface) of an ordinary absorbent pad, whereby the effluent introduced into the absorbent pad is absorbed into the superabsorbent polymer (core). Even if leakage (leakage) occurs through the liquid permeable surface sheet, the leakage blocking sheet adhered to the outer surface (top) prevents the liquid discharge from contacting the skin, and also prevents skin trouble. And can prevent skin and clothing from being contaminated. In addition, the present invention is an absorbent pad formed by superimposing the liquid permeable surface sheet and the liquid impermeable back sheet up and down and fusion of the edges, and embedding a superabsorbent polymer (core) between the liquid permeable surface sheet and the liquid impermeable back sheet. It is possible to easily manufacture (produce) by adhering (welding) the leak-proof sheet to the upper surface of the sheet, and also to (leak) the leak-shielding sheet together when adhering (welding) the liquid permeable surface sheet and the liquid impermeable back sheet. In addition, the manufacturing process is not demanding, and by simply adding a leakproof sheet, the manufacturing cost can hardly increase.본 고안은, 액체투과성 표면시트와 액체불
