Abstract
A droplet detection device includes a light emitting element that emits a detection light for detecting shielding of at least one part by a microdroplet discharged from a nozzle of a head of an ink jet printer in a direction intersecting an advancing direction of the microdroplet; a light receiving element; and a pair of wall portions facing each other and enabling the microdoplet to pass therebetween; where the wall portions have one part of a light path of the detection light from the light emitting element to the light receiving element and allows at least one part of the detection light to be reflected and to reach the light receiving element, and the detection light has a width in a direction equal to a spacing in the direction of the wall portions in a region sandwiched by ends on the light emitting element side of the wall portions.
