Abstract
A liquid discharge head includes a heat generating element which generates heat energy used to discharge a liquid; a temperature detecting element which changes in output voltage in response to a change in the temperature of the heat generating element; an electrical power source line and a grounding line electrically connected to each other through the heat generating element to apply a current to the heat generating element; and a pair of lines for temperature detection electrically connected to each other through the temperature detecting element to apply a current to the temperature detecting element. Here, each of the pair of lines for temperature detection is arranged adjacent to the other.
