Abstract
One object of the present invention is to provide a bolometer with improved TCR. The present invention relates to a bolometer including two electrodes provided on a substrate and a bolometer film lying between the two electrodes to connect the two electrodes, wherein the bolometer film includes p-type semiconducting carbon nanotubes, and contact sites of the two electrodes with the bolometer film each consist only of a monometal or alloy having higher work function than the p-type semiconducting carbon nanotubes, or the proportion of a monometal or alloy having lower work function than the p-type semiconducting carbon nanotubes in metals constituting the contact sites of the two electrodes with the bolometer film is 10% by mass or less, or the contact area of a monometal or alloy having lower work function than the p-type semiconducting carbon nanotubes with the bolometer film is 10% or less of the total contact area between the electrodes and the bolometer film.
