A cleaning sheet for cleaning a cleaning target object, comprising:

• a base material sheet having a first surface;
• a fibrous web formed of a fiber material that includes a first part that is bonded to the first surface of the base material sheet and a second part that includes first brush portions, wherein the first brush portions include:
• a first group of spaced apart first brush portions formed in a row in a Y direction measured along a length of the cleaning sheet, and
• a second group of spaced apart first brush portions formed in a row in the Y directon and that is spaced apart from the first group of the first brush portions;
• and
• a second brush portion that is provided to the first surface of the base material sheet and is formed of crushed pulp materials that are layered, wherein the second brush portion is located between, and spaced apart from, an entirety of the first group of the first brush portions and an entirety of the second group of the first brush portions with respect to an X direction that is measured transverse to the Y direction along a width of the cleaning sheet,
• wherein a height of the second brush portion as measured from the first surface is greater than a height of the first part of the fibrous web as measured from the first surface, and
• wherein a rigidity of a fiber constituting the second brush portion is greater than a rigidity of a fiber constituting the first brush portions.
