We report the preparation of highly grain-aligned and densified [Ca2CoO3-δ]0.62CoO2 bulks and their high thermoelectric performance. The highly $c$-axis aligned ($F=0.94$) and densified samples with low resistivity at room temperature (${\sim}5$ m$\Omega$$\cdot$cm) were obtained by the combination of magnetic alignment and spark-plasma-sintering (SPS) methods. Resistivity $\rho$ and Seebeck coefficient $S$ along the $ab$ plane were systematically changed with oxygen content and, consequently, a power factor (${=}S^{2}/\rho$) was enhanced up to $3.5\times 10^{-6}$ W$\cdot$cm-1$\cdot$K-2 at 300 K for the sample annealed at 500°C in air.
