An improved vehicle information display apparatus made capable of notifying vehicle information, such as a vehicle speed, an engine revolution speed or water temperature to a user instantly and continuously with a high accuracy. The housing portion includes body defining an axial passage. The ingredients are hydrated and extruded through an orifice adapted to produce a puffed snack piece shaped like a peanut and cut into puffed snacks. Then, the cooling recipient is placed onto an electromagnetic heater. The organic light emitting diode includes an anode layer, and a conductive layer is formed on the power supply line. The patterned ultraviolet sensitive photoresist, the patterned oxide regions, and the patterned carbon based material layer are subsequently removed.
