PROBLEM TO BE SOLVED: To provide a liquid level detection device that tightly and rotatably supports a holder to a frame.SOLUTION: In a liquid level detection device comprising: a holder 2 that rotates a circuit substrate accompanied by a motion of a float operative following a liquid level; a terminal that has an elastic piece including a contact part in contact with an electrode part of the circuit substrate 4; and a frame 1 that incorporates a part of the terminal, the liquid level detection device comprises a shaft bearing part 14 that rotatably supports an end of a float arm 3 to be supported to the holder 2 in an outer periphery part of the frame 1. In the holder 2, there are provided a holding part 2B that has a circuit substrate reception part (upper piece) 2A and a lower piece 2B2 to be placed across the shaft bearing part 14, and a concavity for inserting the shaft bearing part between the circuit substrate reception part 2A and the lower piece 2B2. |
