ELECTRONIC COMPONENT ENCLOSURE

To provide an electronic component enclosure that reduces a used amount of a sound insulation material without thickening the enclosure of an electronic component, and ensures a sound insulation effect of sound insulation sheet members without causing a bonding failure of the sound insulation sheet members.SOLUTION: Provided is an electronic component enclosure 21 for storing an electronic component 20. The enclosure has a plurality of surfaces including opposed surfaces 66 to 68 opposed to the electronic component. The plurality of surfaces are connected with crossing parts interposed therebetween. The surfaces are provided with sound insulation sheet members 101 to 103 on at least one of the inner side of the opposed surfaces opposed to the electronic component and the rear side of the opposed surfaces not opposed to the electronic component. The sound insulation sheet members each have a sheet-like sheet surface in contact with the surfaces and a plurality of protrusions provided on the sheet surfaces. The sound insulation sheet members are provided on at least one of the surfaces away from the crossing parts.SELECTED DRAWING: Figure 3 【課題】電子部品の筐体を厚くすることなく、遮音材の使用量を少なく、さらに、遮音シート部材の貼り付け不良を生じさせることなく遮音シート部材の遮音効果を確保した電子部品筺体を提供する。【解決手段】電子部品２０を納める電子部品筐体２１であって、筐体は、 電子部品と対向する対向面６６～６８を有する面部を複数有し、複数の面部同士は、交差部を介して接続され、面部は、対向面における電子部品と対向する内側と、電子部品と非対向であり対向面の裏側と、の少なくとも一方に遮音シート部材１０１～１０３が設けられ、遮音シート部材は、面部と接するシート状のシート面と、シート面に設けられた複数の凸部とを有し、遮音シート部材は、面部の少なくとも一つに、交差部と離間して設けられている。【選択図】図３
