Life Cycle Assessment examines the impacts on resorce and energy consumption and environment at each stage of production, through comsumption and final disporsal. This study examines the impacts on resource and energy by disporsable and reusable diapers use at comsumption stage. For this paper, we look into the actual condition through quationnare etc. So we get the following results.(1) Disporsable only and both kind of diapers use make up over 95%. There are some reasons, a good sleep of child and mother, a saving of time and labor for washing, so that on.(2) Reusable diaper use has higher charges for public services only, but including for purchase disporsable one is 3.7 times cost than the other.(3) On environmental impacts, mainly, reusable diaper use is a burden to the sewage disporsal plant. Disporsable diaper use generates more solid waste than reusable diaper.
