PROBLEM TO BE SOLVED: To obtain a shielding case whereby the soldering faults of S-surface mounting components, the increase in manual soldering works, and the like are prevented. SOLUTION: A shielding case 200 mounted on a printed wiring board 100 has an opening portion 201, formed out of a plurality of square holes and for injecting thereinto a moisture-proof coating agent 130, in the region corresponding to the upper-side region of an IC 101 required to be coated with the moisture-proof coating agent 130, when mounting it on the printed wiring board 100. Further, the shielding case 200 has a protrusive wall portion 202 for preventing the diffusion of the moisture-proof coating agent 130, in the peripheral edge of the region wider than the opening portion 201 of the shield case 200.
