Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a secondary battery capable of suppressing a deterioration due to temperature rise.SOLUTION: A secondary battery includes a metal case, a core capable of being housed in the case, and an electrolyte filled in the case where the core is housed. The core includes: a core body including a positive electrode and a negative electrode alternately laminated with a separator sandwiched therebetween; and a resin layer surrounding the core body and electrically insulating between the core body and the case. At least one of the resin layer and the separator incorporate diamond particles.SELECTED DRAWING: Figure 1 【課題】温度の上昇による劣化を抑制することができる二次電池を提供する。【解決手段】二次電池は、金属製のケースと、ケースに収納可能なコアと、コアが収納されたケースに充填された電解液と、を備える二次電池であって、コアは、セパレータを含んで正極と負極とが交互に積層されたコア本体と、コア本体を囲繞するとともに、コア本体とケースとを電気的に絶縁する樹脂層と、を含み、樹脂層又はセパレータの少なくとも一方は、ダイヤモンドの粒子を内在することを特徴とする。【選択図】図１
