The utility model provides a liquid level detection device and sample analytical equipment, even if via supply with the piping with the liquid supply of electrolyte to the condition of nozzle under, also can well carry out liquid level detection. The liquid level detection device has: the nozzle of tube -shape has electric conductivity for the first liquid of storing in the attraction storage portion, lifting unit makes the nozzle and goes up and down for the liquid level of the first liquid stored in the storage portion, the test section is because the change detection of electrostatic capacitance utilizes the front end of the nozzle of lifting unit lift whether to reach the liquid level of first liquid, supply with the piping, be connected with the nozzle with communicateing, attraction portion sets up in supplying with the piping, the front end of nozzle soak attract the nozzle with first liquid under the state in first liquid in, discharge portion sets up in supplying with the piping, will follow the seco
