Since the case storage chamber 151A does not protrude below the lower surface 5204 of 151A, the case storage chamber 151A may be formed in a size that can accommodate the second battery 4 having a large thickness, and thus the vertical dimension of the battery storage chamber 151 is suppressed. This is advantageous.

Further, according to the image pickup apparatus 100 of the second embodiment, the battery is accommodated in the battery accommodating chamber 151 while the battery engaging wall 1002 is placed on the placement surface 156 of the case accommodating chamber 151A, and the connector portion accommodating chamber. Since the lower surface of 151B is provided at a location displaced closer to the upper surface 5202 of the case storage chamber 151A than the lower surface 5204 of the case storage chamber 151A, each contact piece 60 of the electronic device side connector 50 is connected to the lower surface 5210 of the connector portion storage chamber 151B. Can be positioned at a location above the lower surface 5204 of the case storage chamber 151A, so that the electronic device-side connector 50 protrudes below the lower surface 5204 of the case storage chamber 151A. Therefore, the case storage chamber 151A is formed with a size that can accommodate the second battery 4 having a large thickness. It may be Re is advantageous in the vertical dimension of the battery housing chamber 151 in suppressing.
Further, in the imaging apparatus 100 according to the second embodiment, the engagement wall 1002 is placed on the placement surface 156, the connector portion 30 is connected to the electronic device-side connector portion 50, and the case 10 is accommodated in the case accommodation chamber 151A. In this state, the upper surface 10C of the case 10 and the surface 154A of the lid 155 opposite to the upper surface 10C are close to each other, so that the battery case 10 can function as a reinforcing plate for the lid 154 of the imaging device 100. This is advantageous in reducing the thickness of the main body case 102 of the imaging apparatus 100 and reducing the size.
