Internet use has an important impact on the elderly health. Based on the data of China General Social Survey (CGSS) in 2017, Model 4 and Model 14 in PROCESS were used to test the mechanism of Internet use on the mental health of the elderly, and further compare the differences between urban and rural elderly. The results are that Internet can positively predict the mental health of the whole sample and the urban elderly, but it has no significant predictive effect on the rural elderly; Internet can negatively predict the alienation of whole sample and urban and rural elderly; Alienation has a partly mediated effect between internet use and mental health of the whole elderly; "Internet using—alienation—mental health" the second path was moderated by embodied cultural capital in the whole sample and in the urban elderly. The conclusions are that Internet has a protective effect on the mental health of the elderly, and the mental health can be improved by reducing alienation. Increasing the use of the Internet and embodied cultural capital is an effective way to improve the mental health of the elderly. It is necessary to provide more internet access opportunities for the elderly, especially those in rural areas, increase the accessibility of embodied cultural capital, and bridge the digital divide between urban and rural elderly.
