PROBLEM TO BE SOLVED: To provide a contact structure of a vibration sensor, which achieves the prevention of increase in bulk.SOLUTION: A non-through hole 2 which penetrates through a base plate 1 in a thickness direction of the base plate 1 is provided at a required position on the base plate 1. A pair of contacts 3, 4 which seal the non-through hole 2 from both front and back sides of the base plate 1 are mounted on the base plate 1. A contact ball 5 which can move, relative to the pair of the contacts 3, 4, between a contact position where both of the contacts 3, 4 are electrically connected and an alienation position where both of the contacts 3, 4 are not electrically-connected is arranged in the non-through hole 2. |
