A sound absorption structure body has a housing has a front side and a side face raised at at least a part of an outer edge section of the front face, a gas adsorption body placed in the internal space, surrounded by the front face and the side face, of the housing and physically adsorbing gas in the internal space, a sealing means for sealing the gas adsorption body from the outside, and an acoustic connection section provided at at least either the front face or the side face and functioning as an acoustic mass for acoustically connecting the internal space of the housing and the space outside the housing. The sound absorption structure body achieves both sound absorption in a low -pitched sound range and downsizing of the sound absorption structure body itself.
