The absolute differential cross section for small-angle proton elasticscattering on the proton-rich $^8$B nucleus has been measured in inversekinematics for the first time. The experiment was performed using a secondaryradioactive beam with an energy of 0.7 GeV/u at GSI, Darmstadt. The activetarget, namely hydrogen-filled time projection ionization chamber IKAR, wasused to measure the energy, angle and vertex point of the recoil protons. Thescattering angle of the projectiles was simultaneously determined by thetracking detectors. The measured differential cross section is analyzed on thebasis of the Glauber multiple scattering theory using phenomenologicalnuclear-density distributions with two free parameters. The radial densitydistribution deduced for $^8$B exhibits a halo structure with theroot-mean-square (rms) matter radius $R_{\rm m} = 2.58 (6)$ fm and the rms haloradius $R_{\rm h} = 4.24 (25)$ fm. The results on $^8$B are compared to thoseon the mirror nucleus $^8$Li investigated earlier by the same method. Acomparison is also made with previous experimental results and theoreticalpredictions for both nuclei.
