An electromagnetic-wave shielding device for shielding unnecessary electromagnetic radiation by covering a printed circuit board which generates electromagnetic waves, by a pair of box-like upper and lower shielding cases integrally connected to each other, include an engaged portion provided at a lower shielding case, an engaging portion provided at an upper shielding case of the shielding case pair and engaging with and disengaging from the engaged portion, and pillar-shaped portions being projected from opposing portions of the shielding cases for holding the board between the pillar-shaped portions when the engaged portion of the lower shielding case engages with the engaging portion of the upper shielding case. The printed circuit board held between the pillar-shaped portions is detachably accommodated in the shielding case pair, except for a connect for receiving external signals.
