PROBLEM TO BE SOLVED: To provide an electromagnetic wave shield and a waterproof structure casing which ensures steadiness in contact properties of the casing parts and thus ensures good hermetic and conductive conditions at the time of fitting the casing parts to each other, irrespective of the material of the casing parts and unevenness in the processing accuracy of the casing parts. SOLUTION: A spur 4 consisting of a lower compression member and an upper conductive member is formed in a groove 3 which is provided at a fitting surface of the casing part 1 in a casing structure. The compressible member is formed through a spur method by directly applying an elastic material (soft silicon 7) of low hardness with compressibility to the groove 3. The conductive member is formed through a spur method by directly applying a hard material (hard silicon 8 comprising metal filler) of high hardness with elasticity to the surface of the soft silicon 7. When fitting the casing parts 1, 2 to each other, the spur 4 is elastically deformed, pressed and dented to generate repulsive force, whereby the basic performance of a seal portion is stabilized and ensured.
