Abstract: A non-aqueous electrolyte secondary battery includes: a negative electrode active material represented by the Formula (1)=? (Si material)+? (carbon material), wherein the Si material is one or more kinds selected from the group consisting of SiOx that is a mixture of amorphous SiO2 particles and Si particles and a Si-containing alloy; ? and ? represent % by mass of each component in the layer; and 80??+??98, 0.1???40, and 58???97.9 are satisfied, and a difference between the maximum value and the minimum value of an area proportion (%) of a binder in an area of the field of view of each image of cross-sections of the layer in a case where a plurality of arbitrary places is selected in a plane of the negative electrode active material layer is within 10%.

Abstract: A heat radiating structure of an interior member is provided with a heat radiating portion adapted to be applied to a vehicle and disposed on a rear surface of an interior member whose surface is adapted to be applied with external energy, a heat receiving and radiating portion connected to a vehicle body of the vehicle, and a reflecting member allowing heat radiation, radiating from the heat radiating portion to an inside of the interior member, to be reflected and propagated to the heat receiving and radiating portion. The reflecting member cooperates with the heat radiating portion and the heat receiving and radiating portion to define a closed space.
