A tongue piece is formed to connect the tip of the terminal and the electric line on the insulating substrate incorporated inside the main body, and is filled between at least the terminal holding hole of the main body facing the outside of the tank and the terminal. A liquid level detection device characterized by being sealed with a liquid interposed therebetween.
