PROBLEM TO BE SOLVED: To provide a pet sheet that satisfies both excellent permeability of discharged liquid and wetback of liquid absorbed in an absorbing core. SOLUTION: The pet sheet 1 includes a surface sheet 2, a back sheet 3, the absorbing core 41 and compression molded products 5 of a powdered product of a plant-derived material to swell and collapse by water absorption between the surface sheet 2 and the absorbing core 41. The compression molded products 5 are intermittently arranged on the absorbing core 41 so as to have a plurality of arrangement parts 5A and non-arrangement parts 5B. The non-arrangement parts 5B permeate liquid before water absorption of the compression molded products 5 and have sizes to prevent permeation of liquid by covering with hydrated collapsed products of the compression molded products 5 caused by water absorption after water absorption.
