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.
