Abstract: A sterilization apparatus having UV light capable of assembling to a container is provided. The sterilization apparatus having UV light includes a body, a light-emitting component and a heat dissipating component. The body is detachably assembled to an opening of the container to contact a fluid in the container. The light-emitting component is disposed on the body and emits UV light to irradiate the fluid in the container. The heat dissipating component is disposed in the body and is thermally coupled to the light-emitting component. The body exposes part of the heat dissipating component, such that the heat dissipating component contacts the fluid in the container.
