The inner edge of a hole 23 surrounding the outer circumference of a first heat sink 61 includes two edges 23a and 23b that are positioned on opposite sides to each other with the first heat sink 61 therebetween. An upper frame (shield) 20 includes spring portions 24 on one edge 23a, which is in contact with the first heat sink 61 to push the first heat sink 61 toward the other edge 23b. Further, the upper frame 20 includes, the other edge 23b, a position determining portion 25 to which the first heat sink 61 is pressed. According to the above electronic apparatus, it is possible to define the position of a metallic component by a shield covering a circuit board and to cause the metallic component and the shield to be in contact stably.
