A heater with temperature detecting device, arranged to accurately detect the temperature of a laminated sheet heater over long periods, and a battery structure including the same. A first embodiment includes a laminated sheet heater and a temperature sensor having a temperature measuring portion. The laminated sheet heater includes first and second insulating resin films, a heater element, a first metal sheet, and a second metal sheet and includes a heater metallic section in which, any one of only the first metal sheet and only a combination of the first metal sheet and the second metal sheet is arranged in a lamination layering direction of the laminated sheet heater. The temperature sensor is fastened to the heater metallic section with a flat rivet and fixed to an outer surface of the first metal sheet with the temperature measuring portion in contact with the first metal sheet.
