The present invention is an insulation tape which is characterized by comprising: a mica layer that contains mica; a reinforcement layer that is laminated on the mica layer and contains a filler and a fiber reinforcing material; and a flat plate layer that is laminated on the reinforcement layer and contains flat plate-like inorganic particles having aspect ratios of 30 or more. This insulation tape is prevented from outflow of a filler, which has been loaded thereon in advance, to the outside during the production (especially during hot pressing) of a stator coil, and is capable of forming an insulated coated body that has high thermal conductivity. La présente invention est une bande d'isolation qui est caractérisée en ce qu'elle comprend : une couche de mica qui contient du mica ; une couche de renfort qui est stratifiée sur la couche de mica et contient une charge et un matériau de renfort en fibre ; et une couche de plaque plate qui est stratifiée sur la couche de renfort et qui contient des particules inorganiques en forme de plaque plate ayant des rapports d'aspect de 30 ou plus. Cette bande d'isolation évite le débordement d'une charge, qui a été chargée sur celle-ci en avance, vers l'extérieur durant la fabrication (en particulier durant le pressage à chaud) d'une bobine de stator, et est apte à former un corps revêtu isolé qui possède une conductivité thermique élevée.
