Abstract
The invention presents a gas sensor low in cost and easy to form a terminal member, a gas sensor cap connected to the gas sensor for sending an output signal to an external device, and a gas sensor unit capable of holding a stable electrically connected state between the terminal member of the gas sensor and the gas sensor cap. The gas sensorof the invention includes a gas detecting elementand a terminal member. The terminal memberis made of a plate material bent and processed into a predetermined shape, and includes a tubular output-side terminal portionelectrically connected to a cap terminalfor sending an output signal of the gas detecting element, which is the output-side terminal portionexpanding elastically in diameter when connected to the cap terminal, and a tubular element-side terminal portionconnected electrically to an inside electrode, which is the element-side terminal portioninserted into the gas detecting elementwhile contracting elastically in diameter.
