A disposable absorbent pad comprising a pad, an annular elastic waist band and two pairs of elastic suspending straps bonded to said waist band, said pad comprising a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorbent core sandwiched between said topsheet and said backsheet, wherein side flaps extend outward from laterally opposite side edges of said core, said side flaps having sleeves at their outer side edges, said sleeves each containing elastic members being longitudinally stretchable, said elastic members extending beyond longitudinally opposite ends of the respective sleeves and these elastic members further defining said pairs of suspending straps, said side flaps are folded inward, and longitudinally opposite ends of said side flaps thus folded inward are fixed to said pad, and wherein a longitudinally front end of said pad is connected to a front side of said waist band by one of said two pairs of suspending straps and a longitudinally rear end of said pad is connected to a rear side of said waist band by the other of said two pairs of suspending straps.

### Claim 2 (depends on 1)

A disposable absorbent pad according to claim 1, wherein each pair of strap is connected to said waist band at two positions further spaced from each other than two positions at which this pair of straps is connected to one of longitudinally opposite ends of said pad.

### Claim 3 (depends on 1)

A disposable absorbent pad according to claim 1, wherein said side flaps are formed by at least portions of said topsheet and said backsheet extending from the laterally opposite side edges of said core.

### Claim 4 (depends on 1)
