Abstract: In order to reduce the cost of producing AC adapters of a plurality of models, an AC adapter product group is constituted by AC adapters of a plurality of models. An AC adapter of each model includes a power supply module including a plug (11), a pair of electrodes (12) configured to be electrically communicated with the plug (11), and an internal frame (second frame 132) that attaches the plug (11) and the pair of electrodes (12) to a housing (20) and includes the housing (20). The power supply module is common to the plurality of models. The housing (20) is unique to each of the plurality of models.
