The effects of pressure on antiferromagnetic (AFM) and superconducting phasetransitions of 112-type Ca$_{1-x}$La$_{x}$FeAs$_{2}$ were studied, and thein-plane electrical resistivity $\rho_{ab}$ was measured with an indenter-typepressure cell. The AFM phase transition temperatures of $T_{\rm N}$ = 47, 63,and 63 K at ambient pressure for $x$ = 0.18, 0.21, and 0.26 was suppressed byapplying pressure $P$, with superconductivity emerging at critical pressures of$P_{\rm c}$ $\simeq$ 0, 1.5, and 3.4 GPa, respectively. Correspondingly, theslope of $T_{\rm N}$ against $P$ decreased as $dT_{\rm N}/P$ $\simeq$ $-$15 and$-$2 K/GPa for $x$ = 0.21 and 0.26, respectively. Thus, although the AFM phasewas stabilized with La doping $x$, the AFM phase was suppressed by pressure,and superconductivity eventually emerged.
