To provide a simple vibration switch at low cost, and to provide a light-emitting device using the same.

The vibration switch is provided with a button-shaped battery 1 and a metal spring 2 arranged in the vicinity of the electrode (+) of the battery 1 (arranged from a lower surface to a side surface of the battery), and the metal spring 2 sways and contacts the electrode (+) when vibration is generated. Preferably, the metal spring 2 is formed into an easily swaying coil shape having a fixed end part with a small diameter and free end part with a large diameter. The side part of the free end of the metal spring 2 is to sway and contact the electrode (+) of the battery when the vibration is generated.
