However, in case when {TAIL ~ the surface} of a resin, as in a on chip color filter type solid state image pickup device, there exist only a very small number of {HEAD ~ hydroxyl groups}, the surface may be made to be hydrophilic by subjecting it to plasma treatment, ultraviolet ray irradiation, or siloxane layer formation
