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.
