Abstract
An electromagnetic shielding body includes a first member, a second member, and a fixing member. The first member has a cylindrical shape and has an inner wall that is a wall portion that accommodates a circuit element inside a cylinder. The inner wall has an outer shape without corners. The second member covers the inner wall from an outer peripheral surface side and closes an opening of the inner wall. The fixing member has a shape of a string and is arranged on an outer surface of a portion of the second member that covers the inner wall. The fixing member electrically connects the second member and the inner wall over an entire circumference.
Claims15
An electromagnetic shielding body, comprising:
- a first member including a wall portion having a cylindrical shape with an opening and an outer shape without corners in a plan view in an axial direction, and accommodating a circuit element in a cylinder;
- a second member configured to cover the wall portion from an outer peripheral surface side and closes one opening of the wall portion;
- and
- a string-shaped fixing member disposed on an outer surface of a portion of the second member that covers the wall portion and configured to electrically connect the second member and the wall portion over an entire circumference.
An electronic device, comprising:
- a circuit board having a printed board and an electronic component mounted on the printed board;
- and
- an electromagnetic shielding body configured to cover predetermined circuit elements on the circuit board, wherein
- the electromagnetic shielding body includes
- a first member including a wall portion having a cylindrical shape with an opening and an outer shape without corners in a plan view in an axial direction, and accommodating a circuit element in a cylinder,
- a second member configured to cover the wall portion from an outer peripheral surface side and close an opening in the wall portion that is located away from the printed board, and
- a string-shaped fixing member disposed on an outer surface of a portion of the second member that covers the wall portion and configured to electrically connect the second member and the wall portion over an entire circumference.
