Abstract: An infrared sensor element according to the present invention includes a substrate, and a lower electrode layer, a pyroelectric layer, and an upper electrode layer sequentially formed on the substrate. The substrate has a linear thermal expansion coefficient higher than that of the pyroelectric layer, and the pyroelectric layer includes a polycrystalline body having an in-plane stress in a compressive direction. Thus, the infrared sensor element realizes the pyroelectric layer having a high orientation in a polarization axis direction, an excellent pyroelectric property.

Abstract: An optical reflecting device includes a mirror part, a pair of joints, a pair of vibration parts, a plurality of driving parts, and a fixed part. Each of the joints has a first end connected to respective one the facing positions to each other on the mirror part and a second end opposite to the first end, and extends along a first axis. Each of the vibration parts has a central portion connected to the second end of respective one of the joints. A plurality of driving parts are disposed in each of the pair of vibration parts, and rotate the mirror part. Both ends of each of the pair of vibration parts are connected to the fixed part. The beam width defined as the length of each of the joints in a direction orthogonal to the first axis is greater than the beam width of each of the pair of vibration parts.
