Abstract
An electronic apparatus to which an accessory is to be detachably attached includes a plurality of contacts electrically connectable to the accessory and arranged in a row. The contacts include a plurality of functional signal contacts to which signals having functions that are different functions according to a type of the accessory are connected, reference potential contacts, to each of which a reference potential is connected, and contacts that are used to supply power to the accessory or to communicate with the accessory. The functional signal contacts include a first functional signal contact and a second functional signal contact. A distance from the first functional signal contact to a reference potential contact closest to the first functional signal contact and a distance from the second functional signal contact to a reference potential contact closest to the second functional signal contact are different from each other.
