# Current in Diode.

My question is related to the flow of current in a diode.
In a metal, the current is completely due to the flow of electrons (Eventhough, we always consider the conventional direction for current). Whereas, the current in diode is said to be the sum of the component of current due to holes and due to electrons. The electronic current can easily pass through the wire through which the diode is connected but where does the hole current go?
