In the age of spread of ethics, and development of applied and professional ethics, there remains nothing more significant than science and belief being accompanied with human being all times; the fact that without ethics would destroy science. Many philosophical and epistemic traditions have spoken of scientific rules and manners of conduct; nevertheless, it seems necessary for ethics of science to be regarded as an scientific field and study it completely. In spite of many works in the ethics of research, few works may be found on ethics of science and tried to compile ethical regulations in libraries and publishing scientific findings. To develop this sub-field and explain a framework for compiling ethics of science, some primary agents and compoents is necessary. Such necessaries including possibility and necessity for ethics of science, content of the ethics, challenges facing the branch to be compiled and necessary grounds for it to be organized have been studied in the paper.
