PROBLEM TO BE SOLVED: To provide a cleaning sheet with good dust catching property which is not limited in the degree of freedom of a thermal-adhesive long fiber by a junction which joins the thermal-adhesive long fiber and a thermal-adhesive sheet, which does not get stuck on a subject to be cleaned, and which the distance between a weld section and the tip end of the thermal-adhesive long fiber is random. SOLUTION: The cleaning sheet 1A is made of several long fiber bundles 3 oriented in one direction, composed of several fiber junctions 32 extended crossing long fibers 31, bonded on one surface of a substrate material sheet 2. Two or more fiber junctions 32 of the cleaning sheet 1A are placed at predetermined intervals and a multitude of long fibers 31 are cut at several linear cut sections 24 between fiber junctions 32, 32 adjacent to each other. The linear cut sections 24 of the cleaning sheet 1A form two discontinuous lines 24a in parallel with each other which uncut sections 25 are placed alternately. Two discontinuous lines 24a are continuous viewed from the oriented direction of the long fibers. COPYRIGHT: (C)2010,JPO&INPIT
