Abstract

A magnetic shielding apparatus having a high shielding effect. With the magnetic shielding apparatus having an opening (for example, a cylindrical magnetic shielding apparatus provided with a door), the door covering the opening is electrically and/or magnetically connected to a main body by means of electrically and/or magnetically connecting members. The magnetic shielding apparatus is higher in magnetic shielding factor than the conventional magnetic shielding apparatus, and a magnetic field measuring apparatus using the magnetic shielding apparatus, capable of measuring biomagnetism generated from an inspection target (a living body), with higher sensibility than before.
