The present invention aims to provide an improved wearing article allowing the dimension of the leg-openings to be adequately large without causing leakage of urine. A chassis is formed in a crotch region with an opening extending through inner and outer sheets in the thickness direction. The opening extends across the crotch region in a longitudinal direction partially into front and rear waist regions and also extends through parts of respective waist region elastic sheets in the thickness direction. An absorbent panel functioning as a liquid-absorbent structure is attached to the skin-facing surface of the chassis to cover the opening. The liquid-absorbent panel is joined along both side edges thereof to the inner sheet and the waist region elastic sheets by bonding or sealing technique and along front and rear ends thereof to the waist region elastic sheets by bonding or sealing technique.
