Various materials such as the thermal control film, Paint-type coating materials, some kinds of insulators are used for artificial satellites. This report describes results of distributions of the photoemission current, for them excited by ultraviolet-light. The used film samples were two kinds of germanium coating materials. The painting samples were two kinds of white paint materials (inorganic conductive) which are used for the surface of antenna part in artificial satellite. Insulator samples are four materials (PIFE, Alumina, laminate board and soda glass). In addition, two composite samples which are composed of the metal and the insulator are prepared for the measurement of photoemission. The one is an insulator chip pasted on the metal board and the other is a metal chip pasted on an insulator board. The following measurement results were obtained. The photoemission current value of the Au sample around the insulator become smaller than that of metal samples. The distribution of photoemission current of the insulator on the metal influence around the insulator as well as other insulator samples. The photoemission current value of the metal chip on the insulator board is remarkably small as well as that of insulator material.
