Summary:PROBLEM TO BE SOLVED: To prevent excess deformation of a leaf spring due to a load from the outside without increasing a size or thickness of the leaf spring, and to stabilize electric connection of an electronic component.SOLUTION: In a portable telephone (portable terminal), a leaf spring 10 is arranged on a printed board 6, a leaf spring contact part 11 is brought into press contact with the leaf spring 10 and thus a speaker 7 is connected to the printed board 6. When the speaker 7 is attached to the printed board 6, a gap h1 between a surface of the printed board 6 and the leaf spring contact part 11 is made smaller than a free height h2 of the leaf spring 10. A projection part 12 whose height h3 from the surface of the printed board 6 is lower than the gap h1 is provided around the leaf spring 10, and the deformation of the leaf spring 10 when the speaker 7 is pushed in is limited by the projection part 12.
