To provide an electronic apparatus that can prevent electronic components from being separated from a circuit board.The electronic apparatus 10 includes a circuit board 25, an electronic component 28 mounted on the circuit board 25 via solder balls 26, a cover member 30 mounted on the circuit board 25 so as to surround and cover the electronic component 28 and a convex portion 34 provided at the top plate portion 32 of the cover member 30. The convex portion 34 is deformable to a second state protruding on the circuit board 25 side from a first state protruding in the direction opposite to the circuit board 25 side. When the convex portion 34 is deformed in the second state, the convex portion 34 thus deformed can be made in contact with the top portion 28a of the electronic component 28.
