Zusammenfassung:	To provide a fire-spread prevention type cell unit having a battery cell with a fire-spread prevention sheet that easily deforms in response to overheating and expansion of battery cells and maintains the porosity of the sheet by enabling long-term elastic deformation, a method for manufacturing the same, and a battery. The present invention relates to a fire-spread prevention type cell unit including a battery cell and a fire-spread prevention sheet applied to a side located in the arrangement direction of the battery cell, wherein the fire-spread prevention sheet is a porous sponge sheet, and pores inside the fire-spread prevention sheet have an elongated shape with the lengthwise direction of the pores oriented in the thickness direction of the fire-spread prevention sheet, a method for manufacturing the same, and a battery.
