Abstract
According to an aspect, an electrochromic device, includes: two electrodes facing each other in a first direction with an electrochromic material therebetween; an operational amplifier circuit an output of which is coupled to one of the two electrodes; a first wiring line coupled to a positive power supply coupling part of the operational amplifier circuit; a second wiring line provided as a transmission line for the output; a first contact coupling the first wiring line to a light-transmissive conductor layer configured to transmit a positive power supply potential of the operational amplifier circuit; and a second contact coupling the second wiring line to the one electrode. A distance between the first contact and the second contact in a second direction is larger than a distance between a part of the first wiring line and a part of the second wiring line that are aligned in parallel in the second direction.
