Abstract

L'invention a pour objet de fournir un ruban adhésif qui permet de concilier une excellente résistance au pliage, et une excellente absorption des chocs. En outre, l'invention a pour objet de fournir un appareil électronique contenant ce ruban adhésif. Le ruban adhésif de l'invention possède une couche de mousse. Laquelle couche de mousse présente un module élastique de stockage de cisaillement à 23°C mesuré selon une mesure de viscoélasticité dynamique à une fréquence de mesure de １Ｈｚ, supérieur ou égal à ０,３ＭＰａ, et présente un facteur de pertes diélectriques à 23°C mesuré selon une mesure de viscoélasticité dynamique à une fréquence de mesure de １００Ｈｚ, supérieur ou égal à ０,５０.
