Abstract: An electromagnetic wave sensor 1 has electromagnetic wave absorbers disposed side by side in first and second directions, temperature detection portions held by the respective electromagnetic wave absorbers and sets of two arm portions connected to each electromagnetic wave absorber at two connection portions. In a plan view, the arm portions have two first extending portions extending from the connection portions in directions of which components in the second direction are opposite to each other, and two second extending portions extending from the first extending portions in directions of which components in the first direction are opposite to each other. Four sides of a rectangle circumscribing each of the electromagnetic wave absorbers with a smallest area are inclined with respect to the first direction in directions in which each electromagnetic wave absorber is away from the second extending portions with the connection portions as fulcrums.

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.

Abstract: The device includes heat transfer portions, each of which is configured to thermally connect: one electrode provided on one side of a hot junction side and a cold junction side of each thermoelectric conversion element; and a heat transfer member. A base material has recesses on a second surface side, the recesses being provided so as to be recessed in a range of a region which overlaps with interspaces between other electrodes provided on other side of the hot junction side and the cold junction side of the each thermoelectric conversion element in a plan view. A low thermal expansion layer is provided on a surface side of each of the thermoelectric conversion element facing the heat transfer member or a high thermal expansion layer is provided on a surface side of each of the thermoelectric conversion elements facing the recess.
