A questionnaire study was performed for the elementary school children in the 5th and 6th grades (n=3065) and junior high school students in the 2nd grade (n=1345), who had not yet established their ego-identity, in order to investigate the relationship between the establishment of their feeling of self-esteem and the atmosphere of their mealtime at home.   According to their development, students who could enjoy their mealtime not only at school, but also at home, were shown to be decreased. Especially, whether they could enjoy their mealtime at home was shown to be significantly ( p <0.01) related to their family attachment.   The pass model established by the hypothesis that the mealtime atmosphere at home reflected the parent-child relation showed that those who enjoy mealtime at home were more apt to be put their mind at rest and culture their feeling of self-esteem.
