Abstract
An electromagnetic field imaging device according to one aspect of the present disclosure includes a polarizing optical member arranged to face an imaging subject. A modulated light from a laser light source is influenced by an electric field from the imaging subject in the polarizing optical member. The modulated light subjected to the influence of the electric field is imaged as a detection light. The polarizing optical member is supported in a state of being movable in a direction of a plate thickness of the polarizing optical member. The plate thickness of the polarizing optical member is no larger than 1.2 times a minimum void interval of a wiring of the imaging subject.
