Zusammenfassung:To provide an antenna reception device capable of defining a reception sensitivity at a product reception frequency more appropriately, and an electronic clock.SOLUTION: This antenna reception device comprises: an antenna for receiving a radio wave; a substrate 21 having three or more connection pads P1 to P9; and a connection part for connecting two of the connection pads P1 to P9 to the antenna. The substrate 21 includes two or more of at least one of a first electrode connectable to a ground plane G and a second electrode connectable to a feeding point. When there are two or more first electrodes, the substrate has wirings having different first wiring distances from the first electrodes to the ground plane. When there are two or more second electrodes, the substrate has wirings having different second wiring distances of signal lines extending from the second electrodes.SELECTED DRAWING: Figure 4 【課題】より適切に製品の受信周波数における受信感度を定めることのできるアンテナ受信装置及び電子時計を提供する。【解決手段】アンテナ受信装置は、電波を受信するアンテナと、3個以上の接続パッドP1〜P9を有する基板21と、接続パッドP1〜P9のうちいずれか2個とアンテナとの間をそれぞれつなぐ接続部と、を有する。基板21は、接地面Gに接続可能な第1電極及び給電点に接続可能な第2電極の少なくとも一方を2個以上有し、第1電極を2個以上有する場合には、第1電極から接地面までの第1配線距離がそれぞれ異なる配線を有し、第2電極を2個以上有する場合には、第2電極から延びる信号線の第2配線距離がそれぞれ異なる配線を有する。【選択図】図4
