    Abstract: A light detector includes: a substrate; and a membrane which is supported on a surface of the substrate so that a space is formed between the surface of the substrate and the membrane, in which the membrane includes a first wiring layer and a second wiring layer which are opposite each other with a gap extending along a line having a curved portion interposed therebetween and a resistance layer which is electrically connected to each of the first wiring layer and the second wiring layer and has an electric resistance depending on a temperature, and in which a first edge portion at the side of the line in the first wiring layer and a second edge portion at the side of the line in the second wiring layer respectively continuously extend.

    Abstract: A light detector includes a light detecting element and a reference element. The reference element includes a second substrate and a second membrane disposed on a second surface so as to form a void space between the second membrane and the second surface of the second substrate. The second membrane includes a pair of second wiring layers facing each other with a second gap extending along a second line interposed therebetween and a second resistance layer electrically connected to each of the pair of second wiring layers and having an electrical resistance depending on a temperature. An outer shape of the second membrane when viewed from a direction perpendicular to the second surface is a polygonal shape. The second line extends between diagonals facing each other with a geometric center position of the second membrane interposed therebetween when viewed from a direction perpendicular to the second surface.

    Abstract: A light detector includes a substrate, a membrane disposed on a surface of the substrate, a first and a second electrode post supporting the membrane. The first electrode post includes a first main body portion having a tubular shape spreading from a first electrode pad toward a side opposite to the substrate, and a first flange portion provided in an end portion at the side opposite to the substrate in the first main body portion. The first flange portion is provided with a first sloped surface inclined so as to approach the substrate as it goes away from the first main body portion. A first wiring layer reaches an inner surface of the first main body portion through the first sloped surface. The second electrode post and the second wiring layer are formed similarly to the first electrode post and the first wiring layer.
