Two-color photometric light curves (Oh and Chan 1984) of the eclipsing binary TX UMa have been analyzed by the method of differential corrections of the model of Wilson and Devinney(1971). The system found to be simi-detached with cooler and less massive component filling its Roche lobe. The absolute dimensions have been derived from the results of the photometric solutions with spectroscopic elements of Hiltner(1945). It is assumed that the B8V primary component is on the zero age main sequence stage of the core hydrogen burning and the secondary os at the core contraction stage after the shell hydrogen burning stage according to the Iben's (1967) evolutional tracks for 3.0msolar and 1.0msolar.
