Liquid discharge head and liquid discharge apparatus using the same

An apparatus comprising:

• a liquid storage chamber capable of holding a liquid;
• a liquid communication pipe communicating with the liquid storage chamber and being configured to supply the liquid from a liquid tank to the liquid storage chamber by connecting the liquid tank to the pipe to communicate with the liquid tank;
• an electrode pair, each having an outside end portion located outside the liquid storage chamber and detecting a liquid level of the liquid storage chamber;
• and
• an electric contact portion connected to the outside end portion of each electrode of the electrode pair,
• wherein when the apparatus is in use, the electric contact portion is located above the liquid communication pipe, and
• wherein the electrode pair extends through a wall of the liquid storage chamber, with the outside end portions being outside the liquid storage chamber and inside end portions located in the interior of the liquid storage chamber, and the inside end portions are located below the liquid communication pipe.
