This study presents new photoelectric photometry of TW Cam. Fourier analysis of the light curve shows a group of peaks at 43 d. The first return maps of the primary and secondary minima differ remarkably; those of the secondary minima show significantly larger scatter. It is inferred from this difference that the pulsation period of the star is the formal period (i.e., the distance between two primary minima).
