PHYSICAL QUANTITY DETECTION DEVICE AND PRINTING APPARATUS

A physical quantity detection device including a container that is internally formed with an accommodation space accommodating a detection object formed of a dielectric, a first electrode and at least one second electrode that are provided to face each other via the accommodation space, and an electrostatic capacitance detector that detects an electrostatic capacitance between the first electrode and the second electrode using a mutual capacitance method. The physical quantity detection device may include an insulation layer that covers the first electrode and the second electrode, and an electromagnetic wave shield that covers the insulation layer.
