<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: An electronic apparatus comprises: a metal dome sheet 26 having a metal dome 26b elastically deformed by depressing operation of an operation member; and an operation substrate 17 holding the metal dome sheet 26. The metal dome sheet 26 is provided with a ventilation passage 26g for removing the air when the metal dome 26b is elastically deformed; and a metal dome sheet ventilation opening 26a for taking air out of/into the ventilation passage 26g. A wiring part 17z for lightning conductor which discharges static electricity intruding through the metal dome sheet ventilation opening 26a, is arranged at a position of the ventilation passage 26g between the metal dome sheet ventilation opening 26a and the metal dome 26b.</p> |
