ドの防塵構造。[Claims for Utility Model Registration] (1) An upper sheet on which an upper electrode for a key switch is formed, a lower sheet on which a lower electrode facing the upper electrode is formed, and an electrode interposed between both sheets. In the dustproof structure of a membrane keyboard, which consists of a spacer that maintains the spacer at a predetermined interval, an adhesive sheet to which the lower sheet is adhered, and a bracket fixed to the bottom surface of the adhesive sheet, the air vent hole of the lower sheet is connected to the spacer space. A membrane keyboard characterized in that: an air vent hole in the bracket is provided at a position sufficiently distant from the key switch position, and a hole is provided in the adhesive sheet to communicate the air vent holes. Dustproof structure. (2) The dustproof structure of the membrane keyboard according to claim (1) of the utility model registration claim, wherein the holes in the adhesive sheet have a long hole shape that communicates with a plurality of air vent holes in the lower sheet.
