Structure body and electromagnetic wave sensor

Abstract

A structure body includes: an electromagnetic wave detector; and a pair of arm portions that are positioned on both sides with the electromagnetic wave detector interposed therebetween. The electromagnetic wave detector includes a temperature detection element and an electromagnetic wave absorber which covers at least a part of the temperature detection element. Each of the arm portions includes a wiring layer which is in a line shape and electrically connected to the temperature detection element, and protective layers, a part of each of which is disposed on corresponding one of both sides of the wiring layer. The protective layers are made of a material having a lower thermal conductivity than the wiring layer. In a short direction of the protective layers in a plan view, the wiring layer is positioned on an inward side of both end portions of the protective layers in the short direction.
