To provide a long induction heating apparatus of which electric wire for induction heating can be easily replaced without demolishing a structure and which is simple in structure and can be manufactured at low cost, and a water gate using the same.
An long induction heating apparatus includes: H-shaped steels 21, 25 used as an induction-heated long heat generator in a building structure of a water gate; a pair of guide tubes 35 attached on the side face of the H-shaped steels so as to be directed in the longitudinal direction thereof; a pulley 39 provided at one end of the H-shaped steel 25; covered electric-wires 41 with an intermediate part wound around the pulley 39 and with the other part inserted in the guide tubes 35; and a high-frequency wave power source 42 connected with both ends of the covered electric-wires 41 pulled out of both ends of the guide tubes and induction-heating the H-shaped steels 21, 25 by energizing the covered electric-wires 41.
