The wire is produced by casting an aluminum alloy prepared by rapidly solidifying a molten aluminum alloy having the above composition, producing the wires by subjecting the alloy to plasticity processing, producing the conductor by bunching the wires, subjecting the wires or the conductor to annealing at 250° C. or higher, and then covering the conductor with the insulator.

Abstract: In a store providing system, an action history recording device records the action history of a user. A product information acceptor accepts information to identify content to be sold in a store. Here, the product information acceptor accepts the information to identify content included in the action history of the user in the action history recording device. A content disposing section disposes accepted information relating to content in the store. A target sales holder holds a target number of sales of content and a content price holder holds the price of the content. A price decider increases the price of the content if the counted number of sales is equal to or larger than the target number of sales, and decreases the price of the content if the counted number of sales is smaller than the target number of sales.
