The spacecraft is covered with insulating materials such as multilayer insulation and sunlight reflector. When exposed to high-energy charged particles on orbit, charging and discharging are caused, which may lead to operational abnormality. For the purpose of grasping charged properties, in this study, an electron beam irradiation test with different irradiation current density was carried out using OSR and fluorine insulating material which is a wire harness material. As a result, it was found that charge accumulation behaviors in the material are different depending on irradiation current density. We also reported the relationship between deterioration progress of materials due to repeated irradiation and charge accumulation.
