An endoscope (10) includes a substrate member (50) and a cable (60) including an electric wire (61), a shield member (67), and a drain cable (63). The drain cable (63) has electrical conductivity and a same outer diameter approximately as that of the electric wire (61). The drain cable (63) is electrically connected to the shield member (67) to electrically connect the shield member (67) to the substrate member (50), and is electrically separated from the electric wire (61).
