The purpose of this study was to find out the degree of satisfaction of body image and sex-role identity of primary school boys and girls and to examine their relevance between two sex groups. The data from study would be useful for mapping out some measures for school health education. Two hundred and forty five(245) students of 6th grade from 5 different primary schools in Seoul city and Gyonggi Province were selected for the study. The meaningful difference among demographic sociological characteristics between boys and girls has been shown to be in religion($x^2$=6.705, p=.044), the order of siblings($x^2$=7.455, p=.024), mother's academic career ($x^2$=6.705, p=.035) and the levels of living ($x^2$=4.108, p=.043). In the frequency distribution of sex-role identity, boys and girls were revealed as : undifferentiated 41.0%, 36.4%; as androgynous 24.8%, 25.8% respectively. Boys have masculinity (23.1%), on the other hand girls more feminity (22.7%). The meaningful difference of the degree of satisfaction of body image depends on father's ag(t=3.029, p=.050), mother's occupation(t=2.878, p=.023), home atmosphere(t=9.056, p=.000), level of livin(t=2.216, p=.028), academic achievements(t=4.580, p=.011). Masculine sex-role identity has shown its meaningful difference in mother's academic background(t=7.042, p=.001), academic achievements(t=14.963, p=.000). Feminine sex-role identity according to general characteristics shows meaningful difference in gender(t=2.683, p=.008), the order of siblings(t=3.019, p=0.51), father's academic career(t=5.558, p=.004) mother's academic background(t=7.676, p=.001), mother's occupation (t=3.405, p=.010), home atmosphere(t=4.492, p=.012), school performance(t=16.774, p=.000). Sex-role identity influences on the degree of satisfaction of body image as the relation bet ween the degree of satisfaction of body image and sex-role identity is pro correlative.
