To provide an infrared detector that includes an infrared absorber having a high absorption rate, and an infrared imager.SOLUTION: An infrared detector 100 comprises an infrared absorber 110, a heat converter 112, and an electrical signal detector 114. The infrared absorber is arranged on the heat converter, and is used to absorb infrared rays and convert the infrared rays into heat. The electrical signal detector is used to detect an electric performance change in the heat converter. The infrared absorber includes a plurality of carbon nanotubes and a plurality of carbon particles, the plurality of carbon nanotubes form a network structure, and the plurality of carbon particles are arranged inside the network structure.SELECTED DRAWING: Figure 26 【課題】高吸収率を有する赤外線吸収体を含む赤外線検出器及び赤外線イメージャーを提供する。【解決手段】赤外線検出器１００は、赤外線吸収体１１０、熱変換器１１２及び電気信号検出器１１４を含む。赤外線吸収体は、熱変換器に配置され、赤外線を吸収し、赤外線を熱に変換することに用いられる。電気信号検出器は、熱変換器の電気性能変化を検出することに用いられる。赤外線吸収体は、複数のカーボンナノチューブ及び複数の炭素粒子を含み、複数のカーボンナノチューブがネット状構造を形成し、複数の炭素粒子がネット状構造の内部に配置される。【選択図】図２６
