A cleaning sheet (1A) of the invention includes: a substrate sheet (2); and at least one long-fiber bundle (3) disposed on at least one side of the substrate sheet (2) and made by aggregating long fibers (31) oriented in substantially one direction. The long- fiber bundle (3) is formed by joining the long fibers (31) together with a fiber joining section (32) extending linearly in a direction orthogonal to the orientation direction of the long fibers (31). The cleaning sheet (1A) is formed by joining the thus-formed long-fiber bundle (3) to the substrate sheet (2) by at least one sheet joining section (21). The cleaning sheet (1A) is formed such that the entire fiber joining section (32) or at least a portion of the fiber joining section (32) is not joined to the substrate sheet (2) and the sheet joining section (21) is in perpendicular contact with the fiber joining section (32).

La présente invention concerne une feuille de nettoyage (1A) qui comprend une feuille de base (2) et au moins un groupe de fibres longues (3) disposé sur au moins l'une de ses surfaces, composé de fibres longues (31) orientées sensiblement dans une direction. Le groupe de fibres longues (3) a été formé en reliant les fibres longues (31) les unes aux autres avec une partie de liaison de fibres (32) se prolongeant de façon linéaire dans la direction perpendiculaire à l'orientation des fibres longues (31). La feuille de nettoyage (1A) a été formée en liant le groupe de fibres longues (3), qui a été ainsi formé, à la feuille de base (2) par le biais de parties de liaison de feuilles (21). Dans la feuille de nettoyage (1A), toute la partie de liaison de fibres (32) ou au moins une section de la partie de liaison de fibre (32) n'a pas été liée à la feuille de base (2) et chaque partie de liaison de feuilles (21) a été formée de manière à se trouver au contact perpendiculaire de la partie de liaison de fibres (32).
