A papermaking mat of the present invention has a rectangular shape in a plan view and includes inorganic fibers, a first main surface, and a second main surface facing the first main surface. The first main surface includes multiple raised portions each having a linear shape. When the papermaking mat is viewed in a plan view, the raised portions: are aligned in one direction in a plane direction of the first main surface; have an average length of 5 to 200 mm, an average width of 1 to 50 mm, and an average height of 0.05 to 0.50 mm; amount to five or more in a range of a freely selected 10 cm-long×10 cm-wide square of the first main surface; and include a fiber bundle being formed by entangling multiple fibers and twisting together.
