In a housing having a sealing structure providing an electromagnetic wave shielding function and a waterproof function between first and second housing components ( 1, 2 ) which define a space therebetween, the sealing structure includes a groove portion ( 12 ) made in the first housing component to extend around the space, a first seal member ( 13 ) formed by being directly applied into the groove portion, a second seal member ( 14 ) formed by being applied onto the first seal member, and a pressing portion ( 16 ) formed on the second housing component to correspond to the groove portion. The first seal member has relatively low hardness to be compressible. The second seal member has relatively high hardness, flexibility, and conductivity. When the first and second housing component are combined to each other, the pressing portion pressingly deforms the second seal member so as to be brought into surface contact with the second seal member. The first and second housing component are made of magnetic metal.
