The utility model discloses an inhaling sheet with increased area. The inhaling sheet comprises an inhaling substrate (1), positioning holes (2), and half cylinders (3). The inhaling substrate (1), which is a pure-titanium circular ring, has an outer diameter from 150 mm to 165 mm, an inner diameter from 80 mm to 90 mm, and a thickness from 2 mm to 3 mm. The half cylinders (3) with diameters from 0.5 to 1.5 mm are arranged on the inhaling substrate (1) in parallel. The distance between centers of two adjacent half cylinders is from 2 to 3 mm. The pure-titanium circular ring and the half cylinders are produced by pure titanium powder via technology of powder metallurgy and have structures with multiple holes. Three positioning holes (2) are disposed on the inhaling substrate (1). The half cylinders (3) substantially increase contact area between the inhaling sheet and gas. The inhaling sheet with increased area has high inhaling speed by which the inhaling sheet is fixed on a device produced by stainless steel
