Zusammenfassung:	The invention discloses a preparation method of an electromagnetic shielding metal mesh with a space limited by an inner concave surface. The preparation method comprises the following steps: a, preparing a preparation raw material; b, diluting positive photoresist AZ9260 by using acetone and butyrolactone; c, uniformly spraying a diluted photoresist solution into a cylindrical prism to obtain a sample piece; d, putting the obtained sample piece into a constant-temperature oven; e, baking, and etching the sample piece; f, developing the sample piece by using a ZX-238 developing solution after etching; g, washing the developed sample piece in ultrapure water, and blow-drying moisture on the surface of the sample piece; h, after the sample piece is blow-dried, placing the sample piece in a conductive film plating machine, and plating with a metal film, wherein the metal film is made of chromium and silver alloy; i, putting the sample piece obtained after film coating into an N-methylpyrrolidone solution, and ca
