Claim:
1. A sheet-like article comprising ultrafine fibers with an average monofilament diameter of 0.1 μm or more and 7 μm or less and an elastic polymer containing polyurethane as primary component, meeting Formula (a) given below for the ratio between the fiber density (A′) in a layer having a thickness equal to 50% of the total thickness measured from one surface of the sheet-like article, herein referred to as layer (A), and the fiber density (B′) in a layer having a thickness equal to 50% of the total thickness measured from the opposite surface of the sheet-like article, herein referred to as layer (B), meeting Formula (b) given below for the ratio between the density (A″) of the elastic polymer containing polyurethane as primary component in layer (A) and the density (B″) of the elastic polymer containing polyurethane as primary component in layer (B), and having an overall density of 0.2 g/cm 3 or more and 0.6 g/cm 3 or less for the entire sheet-like article:
