Electronic device with improved shielding structure

An electronic device comprising:

• a circuit board having a first surface and a second surface;
• a first member for covering the first surface to function as a shield of the circuit board;
• and
• a second member placed on a side of the second surface, wherein:
• the first member has a first encompassing region surrounding an electronic component mounted on the first surface,
• the first encompassing region has, in at least a portion thereof, a first outer region located on an outer side of an outer edge of the circuit board,
• the second member has a second outer region located on the outer side of the outer edge of the circuit board,
• the second outer region has:
• a first outer fixed portion and a second outer fixed portion fixed to the first outer region, and
• at least two projections located between the first outer fixed portion and the second outer fixed portion in a direction along the outer edge of the circuit board that protrude from a surrounding surface of second outer region,
• the first member and the second member are in contact with each other at the first outer fixed portion and the second outer fixed portion by fasteners, and
• the first member warps upwards away from the surrounding surface of the second outer region at a region where the first member contacts the at least two projections thereby forming a gap between the first member and the second member in a space between the at least two projections.
