A timepiece module includes a digital display screen, an antenna device and a metallic component. The antenna device includes an antenna pattern relevant to communication and an antenna component connected to and extending from the antenna pattern. In a plan view, the antenna pattern has a curved shape and overlaps the digital display screen. The antenna device is disposed such that either one side or other side on a virtual line does not overlap the metallic component. The virtual line is an extending direction in which the antenna component, which extends from the antenna pattern, extends.
