1. A structure body comprising:
an electromagnetic wave detector; and
a pair of arm portions that are positioned on both sides with the electromagnetic wave detector interposed therebetween,
wherein 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,
wherein 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 one of the protective layers being provided on a first side surface of the wiring layer, and a part of another one of the protective layers being provided on a second side surface of the wiring layer that opposes the first side surface,
wherein the protective layers are made of a material having a lower thermal conductivity than the wiring layer, and
wherein in a short direction of the protective layers in a plan view, both ends of the wiring layer in the short direction are positioned inside of both end portions of the protective layers in the short direction.
