<p>PROBLEM TO BE SOLVED: To lower the possibility of infiltration of static electricity between a metal dome and a substrate even if a space between the metal dome and the substrate is not sealed.SOLUTION: A digital camera 100 comprises: an operation substrate 600 having a first switch wiring part 606 and a second switch wiring part 607; and a first metal dome sheet 601 having a metal dome 601a and attaching to the operation substrate 600. The first switch wiring part 606 and the second switch wiring part 607 are electrically connected to each other via the metal dome 601a by depressing a power button 101 so as to press the metal dome 601a. The metal dome sheet 601 is provided with an air path 601g from the periphery of the metal dome 601a to a dome sheet ventilation opening 601e formed on a region facing each other across the almost center of the metal dome 601a.</p> |
