A UV sensor () includes a container () in which the upper end opening of a metal side tube () is sealed with a front plate () composed of borosilicate glass as an incident light window and the lower end opening is sealed with a base plate (). The front plate () serving as an incident light window constitutes part of the wall of container () by sealing the upper end opening of the metal side tube (). A pin-type photodiode () is disposed inside the container (). The pin-type photodiode () comprises a photoabsorption layer () formed from InGaN (0&#x3c;x&#x3c;1) between an n-type contact layer () and a p-type contact layer ().

A vehicular anti-skid control apparatus comprises a differential pressure detector for detecting the pressure difference inside brake lines of separate brake channels, a brake failure detector for detecting failure in one of the brake channels based on the anti-skid control state of each brake channel, a brake failure evaluator for evaluating failure of the brake system based on both output signals of the differential pressure detector and brake failure detector wherein the anti-skid control method is changed from normal anti-skid control to a particular anti-skid control when a brake failure occurs.
