The purpose of this study was to investigate the relationship between team association, team attachment, and team loyalty of male and female spectators of professional basketball through which to verify if there exists a difference according to the spectators of male and female. This study distributed a total of 440 copies of questionnaires(220 for Male and Female, respectively) using a convenient sampling method; then, this study used 416 copies among the collected questionnaires as its final analysis. As the result of making an analysis of a structural equation model in an effort to verify the goodness of fit to the research model and individual hypotheses set up for this purpose, first, game results and team pride were found to have a significant influence on team attachment. Second, team attachment was found not to have a significant influence on team loyalty. Third, in addition, as a result of making a latent means analysis to see if there exists a difference between the major variables of Male and Female, Female showed higher latent means in game energy and fun than Male. Further, as a result of examining the causal relationship between the variables established through the model on which path invariance constraints between groups were placed, it was not found that there existed a difference between empirical models of Male and Female.
