Abstract: PURPOSE: An electronic sunlight blocking device is provided to use a simple electrochromic element which does not have an electrolyte to drastically change a light transmitting rate, thereby blocking light when a current value is larger than a specific value. CONSTITUTION: A first electrode(32) is arranged on a substrate(31). A light transmitting rate changing material(34) is arranged on the first electrode. The light transmitting rate changing material changes a light transmitting rate according to a current quantity. A second electrode(33) is arranged on the light transmitting rate changing material. The light transmitting rate changing material has at least one layer. A light absorbing layer occupies a portion of the light transmitting rate changing material. The light absorbing layer generates currents using sunlight.
