PROBLEM TO BE SOLVED: To provide a capacitance liquid detector capable of preventing a detection error of liquid level height of a liquid such as lubricant, and detecting capacitance accurately, a compressor having the liquid detector, and an air conditioner having the compressor.SOLUTION: A detection element part 10 of a liquid detection unit 1 is configured so that, a facing gap between a pair of electrode plates 40S, 40mS is set to become wide, and a facing gap between a pair of electrode plates 40mL, 40L is set to become narrow. By a detection signal corresponding to the pair of electrode plates 40S, 40mS having the wide facing gap, presence/absence of a liquid, namely, liquid level height is detected. By a detection signal corresponding to the pair of electrode plates 40mL, 40L having the narrow facing gap, capacitance is detected, for detecting a ratio of impurities contained in the liquid.SELECTED DRAWING: Figure 2 |
