PROBLEM TO BE SOLVED: To provide a favorable imaging device for reciprocally identifying and inspecting a first portion and a second portion in a test object including the first portion and the second portion having mutually different wavelength characteristics in the near-infrared light.SOLUTION: The imaging device includes a first pixel and a second pixel. The light receiving sensitivity of the first pixel is maximum in the vicinities of mutually different first wavelength and second wavelength in the near-infrared wavelength band respectively. The light receiving sensitivity of the second pixel is maximum in the vicinity of the second wavelength. The light receiving sensitivity of the second pixel in the first wavelength is 10% or less of the light receiving sensitivity of the first pixel in the first wavelength.【課題】近赤外において、互いに異なる波長特性を有する第１部分および第２部分を含む被検体における該第１部分および該第２部分を相互に識別して検査するために有利な撮像装置を提供する。【解決手段】撮像装置は、第１画素および第２画素を含み、前記第１画素の受光感度は、近赤外の波長帯域における互いに異なる第１の波長および第２の波長のそれぞれの付近に極大値を有し、前記第２画素の受光感度は、前記第２の波長の付近に極大値を有し、前記第２画素の前記第１の波長における受光感度が、前記第１画素の前記第１の波長における受光感度の１０％以下である。【選択図】図１
