摘要

PROBLEM TO BE SOLVED: To provide a breathable sheet in which the breathability of the thickness direction is excellent, and the foreign matter adhered thereon is easy to be visually checked.

SOLUTION: The breathable sheet 4 is breathable in the thickness direction. The breathable sheet 4 includes: a resin film 9 in which a plurality of straight holes 12 are formed linearly passing through in the thickness direction; and a white-colored layer arranged atop a main surface 4b of the resin film 9 and/or of white-colored particles 10 dispersed into the interior of the resin film 9. The diameter of the plurality of straight holes 12 is 20 μm or less. The whiteness of at least one main surface 4b in the breathable sheet 4 is 70 or more.
