ABSTRACT:
A thermal-type infrared detecting element is provided which includes an infrared detecting member, a support member supporting the infrared detecting member, a substrate holding the support member, and a low thermal conduction part intervening between the substrate and a central portion of the support member, the support member having a link portion in at least a peripheral portion thereof which links the support member to the substrate and slits and/or grooves defined at a location adjacent the link portion. This infrared detecting element exhibits excellent sensitivity and responsiveness while requiring no cooling, and a one- or two-dimensional array of the element assures clear imaging with less crosstalk.
