A laminated body includes: a substrate portion composed of silicon carbide; and a graphene film disposed on a first main surface of the substrate portion, the graphene film having an atomic arrangement oriented with respect to an atomic arrangement of the silicon carbide of the substrate portion. A region in which a value of G'/G in Raman spectrometry is not less than 1.2 is not less than 10% in an area ratio in an exposed surface of the graphene film, the exposed surface being a main surface of the graphene film opposite to the substrate portion.

Laminated body and electronic device

A power load survey apparatus is disclosed with an electronic power sensor for detecting a power load in the form of a pulse signal, a collector cartridge detachably coupled to the electronic power sensor and having a memory for storing the pulse signal and the time of data collection. The time is obtained from a self-contained time keeping circuit. A memory and magnetic tape converting device is detachably coupled to the collector cartridge and includes a magnetic tape device for transferring and recording data from the memory of the electronic power sensor, and a standard clock 52. The time data obtained from the collector cartridge is time rectified to a standard time from the standard clock 52 each time the collector cartridge is coupled to the memory/magnetic tape converting device thereby insuring that the collector cartridge shows a correct time.
