Claim 0:
1. An electromagnetic wave sensor comprising:
electromagnetic wave absorbers that are disposed side by side in a first direction and a second direction intersecting each other within a plane;
temperature detection portions that are held by the respective electromagnetic wave absorbers; and
sets of two arm portions that are in a bent line shape and connected to each of the electromagnetic wave absorbers at two connection portions in each of the electromagnetic wave absorbers,
wherein in a plan view, the two arm portions have two first extending portions extending from the two connection portions in directions of which components in the second direction are opposite to each other, and two second extending portions extending from the two first extending portions in directions of which components in the first direction are opposite to each other, and
wherein in a plan view, four sides of a rectangle or a square circumscribing each of the electromagnetic wave absorbers with a smallest area are inclined with respect to the first direction in directions in which each of the electromagnetic wave absorbers is away from the two second extending portions with the two connection portions as fulcrums.
