Bolometer and method for manufacturing the same

A method of manufacturing a bolometer comprising:

• forming a base material layer by a resin having a thermal conductivity of 0.3 W/mK or less on a support;
• forming an under layer on the base material layer;
• forming a bolometer film on the under layer;
• forming two electrodes so as to be connected to the bolometer film to form a light detector including the bolometer film and the electrodes;
• and
• forming a protective layer having a thermal conductivity of 0.3 W/mK or less and an infrared transmittance of 70% or more in such a manner that the protective layer covers the light detector and bonds directly to the base material layer around the light detector, whereby the base material layer and the protective layer together form a resin exterior enclosing the light detector;
• forming a groove outside of the outer periphery of the light detection part to the depth of the surface of the support;
• and
• separating from the support the light detector enclosed by the resin exterior comprising the base material layer and the protective layer.
