ABSTRACT:
A thermal infrared sensor device includes a substrate having a concave portion, a temperature detecting portion connected to the substrate via a supporting leg held at an upper portion of a space within the concave portion, an infrared reflecting film covering at least a portion of the supporting leg without being thermally connected to the temperature detecting portion, and an absorbing hood portion held opposite the infrared reflecting film and thermally connected to the temperature detecting portion, without being thermally connected to the infrared reflecting film, and extending laterally, in a plate shape, covering at least a portion of the infrared reflecting film.
