There is no influence by static electricity and the destruction of the light emitting member can be eliminated.

The insulating sheet is formed of an attachment sheet for attaching the leaf spring. The attaching sheet is formed with an attaching portion for covering and attaching the upper surface of the leaf spring. A conductive film is formed on the attaching portion, and the attaching sheet is a circuit board. Since it is laminated on one surface side of the leaf spring, the leaf spring is interrupted from the conductive film by the attachment portion, thereby eliminating the influence of static electricity.

The insulating sheet is formed of an attachment sheet for attaching the leaf spring, and the attachment sheet is provided with an attachment portion for covering and attaching the upper surface of the leaf spring, and a conductive film is removed on the attachment portion, and the attachment sheet is a circuit board. Since it is laminated on one side of the sheet, the deterioration (inversion) operation of the leaf spring by the conductive film can be prevented, and the leaf spring is blocked from the conductive film by the attachment portion, thereby eliminating the influence of static electricity. have.

The insulating sheet is formed of an attachment sheet and a spacer sheet attached to the other surface side of the attachment sheet, and because the spacer sheet is laminated on one surface side of the circuit board, a creepage surface between the conductive film and the wiring pattern formed on the circuit board is provided. The distance can be further increased, and the influence of static electricity can be reduced.

In addition, the insulating sheet is formed of a spacer sheet having a concave portion that can accommodate the leaf spring. A leaf spring is attached to the conductive film formed so as to cover the concave portion, and the spacer sheet is laminated on one side of the circuit board. A deformation | transformation (inversion) operation | movement can be made favorable and a thing with favorable operation feeling can be obtained.
