We evaluated the cost of IC package through life cycle stage using the LCC method. It becomes clear that the cost of product production was large in the life cycle stage of product production, use, collection and recycling. We were able to define the use cost, collection cost and recycling cost of IC package by LCC. Next, it was shown that 3 elements of the raw materials, direct expense and direct personal expenses were large, when each element of the product production cost is compared． In this study, the design engineer has come to be able to calculate the product production cost with life cycle thinking.
