Abstract: Problems To provide a method for evaluating characteristics of MZ interferometers in an optical modulator having a plurality of MZ interferometers. Means for Solving Problems When an optical modulator includes a plurality of MZ interferometers, the 0-degree component contains a signal derived from an MZ interferometer other than the MZ interferometers for evaluating the characteristic. For this, it is impossible to accurately evaluate the characteristic of the MZ interferometers. The present invention does not use the 0-degree component normally having the highest intensity. That is, the characteristic of the MZ interferometers are evaluated by using a side band intensity of the component other than the 0-degree component.

Abstract: A liquid storage container prevents quality degradation of liquid caused by evaporation of moisture in the liquid stored in a liquid storage chamber and contact between the liquid and air introduced into the liquid storage chamber. Quality is stably maintained for a long time. As ink contained in a liquid storage chamber is consumed, an atmosphere communicating path guides air into the liquid storage chamber from the outside. The atmosphere communicating path has a thin communicating path at an intermediate position. The thin communicating path is thinner than other portions and is capable of holding ink by a meniscus. An amount of ink sufficient for blocking the ink contained in the liquid storage chamber from the atmospheric air is held in the thin communicating path.
