This paper focuses on in-home care services based on Japan's Long-term Care Insurance (LCI) Law, while aiming to make the following investigations from the viewpoint of Home Economics : 1) theoretical investigations on the LCI type welfare services as socialization of household care work, and 2) examinations of whether or not the low unit price presently set for the home help services is adequate for improving the quality of socialized welfare services. Firstly, we will clarify what kind of housework is included in care work by selecting the items from a series of LCI users' housework from the time they apply for the services to the time they receive them. Secondly, we will show a number of “new household work” (Thiele-Wittig) resulting from the interface between the private household work and the socialized household services. The results are as follows : 1. The care housework is included in all phases of care service from meal, clothing, housing, and household administration. 2. The unit price for home help services is lower than that for nursing care services and the level of priority is also lower. For making justifiable evaluation of home help services, the Home Economics' know-how (family resource/well-being management) should by all means be utilized for dealing with welfare service issues.
