In this paper, we focused on researchers in the engineering field and examined the relationship between career self-reliance and the experience of writing research papers. We conducted a questionnaire survey on the research paper writing experience and career self-reliance for researchers in the engineering field who had experience as professors in higher education institutions. As a result, we found that “A sense of achievement and growth experience gained by writing a research paper” affects both “Psychological aspects of career self-reliance” and “Behavioral aspects of career self-reliance”. Especially, the survey results demonstrated that “A sense of achievement and growth experience gained by writing a research paper” affects “Professional self-efficacy” and “Adaptation behavior to changes in the work environment”.
