Abstract

A cleaning sheet (A) of the invention includes: a substrate sheet (); and at least one long-fiber bundle () disposed on at least one side of the substrate sheet () and made by aggregating long fibers () oriented in substantially one direction. The long-fiber bundle () is formed by joining the long fibers () together with a fiber-joining section () extending linearly in a direction orthogonal to the orientation direction of the long fibers (). The cleaning sheet (A) is formed by joining the thus-formed long-fiber bundle () to the substrate sheet () by at least one sheet-joining section (). The cleaning sheet (A) is formed such that the entire fiber-joining section () or at least a portion of the fiber-joining section () is not joined to the substrate sheet () and the sheet-joining section () is in perpendicular contact with the fiber-joining section ().
