The beta-ray spectra of Co60 and Sc46 were studied by a semicircular beta-ray spectrometer with the radius of 10 cm. The spectrum of Co60 agrees with that of the allowed transition of the Fermi theory from the maximum energy down to about 60 keV. The spectrum of Sc46 also agrees with that of the allowed transition from the maximum energy down to 120 keV. For Co60 the upward deviation which occurs at the energy less than 60 keV may be due to the effect of the source thickness, but for Sc46 the upward deviation at the energy less than 120 keV could not be decisively explained. The maximum energies of Co60 and Sc46 beta-rays are $316\pm 3$ keV and $357\pm 3$ keV, respectively.
