Patent ID: 8570838

Claim:
An electronic timepiece with internal antenna, comprising: a cylindrical external case; a crystal that covers one of the two openings of the external case; a drive mechanism that drives a hand inside the external case; an antenna that has a cylindrical side part made of metal, a metal bottom part that covers one of the two openings of the side part, and a metal top part that extends transversely to the center axis of the side part inside the external case, and contacts the inside surface of the side part, holds the drive mechanism between the bottom part and the top part, and has the top part disposed between the drive mechanism and the crystal; and an annular dielectric that extends circumferentially to the side part and contacts the top part in the axial direction of the side part; wherein the external case has a metal part that is made of metal, the bottom part is a back cover that covers the other of the two openings of the external case, the top part has a slot part that extends circumferentially to the side part and contacts the dielectric, a slot that extends circumferentially to the side part is formed in the slot part, and the dielectric covers part or all of the slot in the axial direction of the side part.
