Abstract: Provided is a stacked secondary battery with which it is possible to prevent the phenomenon of gas generated by an electrode material or the like inside a cell accumulating between an electrode and a separator, and forming bubbles that cannot readily escape, and with which safety performance at high temperatures can be enhanced. A stacked secondary battery in which a positive electrode and a negative electrode are stacked with a bag-like separator interposed therebetween, wherein one of the positive electrode and the negative electrode is accommodated in the bag-like separator, the other of the positive electrode and the negative electrode is stacked on the bag-like separator accommodating said one electrode, and the bag-like separator has a uniaxial contraction characteristic at high temperatures and has a slit formed in a contraction direction along which the contraction coefficient of the bag-like separator is large.

Abstract: An object of the present invention is to provide an infrared sensor having a high TCR value, and a method for manufacturing the infrared sensor. The infrared sensor comprises a substrate, a first electrode on the substrate, a second electrode spaced from the first electrode on the substrate, and a carbon nanotube layer electrically connected with the first electrode and the second electrode, wherein the carbon nanotube layer comprises semiconducting carbon nanotubes in an amount more than 66% by mass based on the total amount of carbon nanotubes and 60% or more of the carbon nanotubes contained in the carbon nanotube layer have a diameter within a range of 0.6 to 1.5 nm and a length within a range of 100 nm to 5 μm.
