either the 140 $\mu$m or the 160 $\mu$m bands. By subtracting the dust-band templates constructed in this paper, we can achieve a similar level of flux calibration of the AKARI far-IR all-sky maps in the $|\beta| < 40\degree$ region to that in the region for $|\beta| > 40\degree$.'

Introduction
============

Zodiacal emission (ZE) is thermal emission from interplanetary dust (IPD). It dominates the diffuse radiation in the mid- to far-infrared (IR) wavelength regime. Since the dust located at around 1 astronomical unit (a.u.) from the Sun has a thermal equilibrium temperature of $\sim 280$ K, the ZE exhibits a spectral peak around 10–20 , which dominates the mid-IR brightness of the diffuse emission in the sky. Even in the far-IR regime, the ZE contribution is non-negligible at high Galactic latitudes, where Galactic radiation is relatively weak. IPD originates mainly from comets and asteroids, and it is distributed across the solar system. The zodiacal dust cloud is characterized by a relatively
