摘要：
[PROBLEMS] To secure the connection of the reference potential contacts between the accessory and the electronic apparatus even if static pressure or impact is applied to the accessory
[SOLUTION MEANS] An electronic apparatus (100) to which an accessory (200) is to be detachably attached includes a plurality of contacts (TA01-TA21) electrically connectable to the accessory and arranged in a row. The plurality of contacts include a contact (TA02, TA03, TA05-TA017, TA19, TA20) that is used for power supply from the electronic apparatus to the accessory or for communication between the electronic apparatus and the accessory, first grounded contacts (TA01, TA21) that are contacts disposed at both ends of the plurality of contacts and are connected to ground, and second grounded contacts (TA04, TA18) that are connected to the ground and are contacts disposed at both ends of part of the plurality of contacts other than the first reference potential contacts in a case where the accessory is connected to the part.
