To provide a health keeping and promoting instrument capable of sufficiently receiving the irradiation effect of far infrared rays from the surface of the skin of a wrist by bonding a far infrared emitting sheet integrated with an adhesive sheet to the rear lid of a wristwatch to apply the same to a wrist.

An adhesive sheet is bonded and fixed to a far infrared emitting sheet having the same shape as the rear lid of a wristwatch. By this constitution, anyone using a wristwatch can sufficiently receive the irradiation effect of far infrared rays by simply bonding the far infrared emitting sheet to the rear lid of the wristwatch and can utilize the far infrared emitting sheet without axiety without obstructing work operation.
