To provide living environment improving charcoal capable of increasing various actions such as adjustment of underfloor humidity, adsorption of bad smell and toxic substance, thermal insulating performance, generation of far infrared radiation, generation of negative ions, reduction of electromagnetic wave, and stabilization of magnetic field by far and improving improvement performance of reduction of stress, suppression of oxidation of a body, improvement of hemokinesis, and life of sound sleep greatly.

This living environment improving charcoal 1 is prepared by sticking powders produced by crushing a mixture containing powders of ceramics far infrared radiation emission material and powders of radiation source material made of radioactive mineral containing at least one kind of natural radioactive element among thorium and uranium to substantially whole face of an outer side face of a wrapping bag 11 having permeability and filling and sealing predetermined amount of active charcoal particles 12 produced by carbonizing wooden chips at 900 or 1,000°C into the wrapping bag.
