Abstract (in Japanese) (See Japanese page) 
(in English) A shielding metal case generally has some junctions of metal plates and electromagnetic field leak from the junctions because of their contact resistance.
The leaked electromagnetic field deteriorates the original shielding effect of the cases.
In this study, the shielding effect versus metal thickness of the metal case was evaluated in kHz band.
A 300 mm cubic case was employed as example of metal cases having junctions and it was composed of aluminum frame and copper plates.
As a result, the leakage affected the shielding effect when the case was made of high-shielding thick metal plates.
To reduce the contact resistance due to the gaps on the junctions, the influence of the material and flatness of the frame on the shielding effect was discussed.
