THREAD BATTERY

A thread battery according to the present invention has a first end and a second end opposed to each other in a longitudinal direction, the thread battery comprising a thread-shaped first electrode extending in the longitudinal direction; a solid electrolyte disposed on an outer peripheral surface of the first electrode; a second electrode disposed on an outer peripheral surface of the solid electrolyte; a first current collector covering the first end; and a second current collector covering the second end. The thread battery is characterized in that the first current collector is connected to the first electrode at the first end and is not connected to the second electrode, and the second current collector is connected to the second electrode at the second end and is not connected to the first electrode. 本发明的线电池的特征在于，是具有在长边方向相对的第1端部和第2端部的线电池，具备：在上述长边方向延伸的线状的第1电极，配置于上述第1电极的外周面的固体电解质，配置于上述固体电解质的外周面的第2电极，覆盖上述第1端部的第1集电体，以及覆盖上述第2端部的第2集电体；上述第1集电体在上述第1端部与上述第1电极连接，不与上述第2电极连接，上述第2集电体在上述第2端部与上述第2电极连接，不与上述第1电极连接。
