Provided are: a non-conductive antibacterial sheet which permits a protrusion/recess micro-pattern shallower than a conventional protrusion/recess micro-pattern and therefore enables the use of more kinds of materials a process for manufacturing the same and a method for inhibiting the growth of bacteria. This non-conductive antibacterial sheet includes a micro-patterned surface which is made of an acrylic resin and which is produced by forming multiple protrusions on the surface of a sheet and thereby forming a protrusion/recess micro-pattern, said multiple protrusions exhibiting nearly rectangular shapes in the plane view, wherein: the protrusions are regularly formed in an x-direction and a y-direction perpendicular thereto with x-direction spaces and y-direction spaces left, said x- and y-direction spaces having prescribed widths the height of the protrusion tops from the sheet surface is 0.4 to 1μm, while the bottom width of the protrusions is 2 to 3μm and the width of the x-direction spaces is equal to the bottom width of the protrusions. Thus, the non-conductive antibacterial sheet exhibits antibacterial effect in such a way that the bacteria which are in static contact with the micro-patterned surface are not trapped in the x-direction spaces.Linvention concerne une feuille antibactérienne non conductrice, qui autorise une microstructure à protubérances/évidements moins profonde quune microstructure classique à protubérances/évidements, et donc permet lutilisation de plusieurs types de matériaux un procédé pour sa fabrication et un procédé pour inhiber la croissance de bactéries. Cette feuille antibactérienne non conductrice comprend une surface microstructurée, qui est constituée dune résine acrylique et qui est produite par formation de plusieurs protubérances sur la surface dune feuille, en formant de ce fait une microstructure à protubérances/évidements, lesdites plusieurs protubérances présentant une forme presque rectangulaire dans une vue en plan, o
