To provide a heating cooker which can almost perfectly prevent inflow of water into a cooling fan and a substrate even if water enters from a suction port.
The heating cooker comprises a ventilation flue for cooling heating coils and a substrate, and a water influx prevention structure. The ventilation flue includes a suction port 41 arranged on the rear side of a main body, an air intake duct 46, and a fan housing 423 communicating with the air intake duct 46, housing a cooling fan 42 and having an exhaust port 47 at the bottom. The water influx prevention structure includes a water influx prevention member 52 covering a lower half of a blade part 421 of the cooling fan 42, a plate-like rib A51 arranged on an inner face of a front wall of the air intake duct 46 so as to face the inside of the air intake duct 46 and protrude obliquely downward, and a rib B53 vertically arranged on the downstream side of the exhaust port 47 of the fan housing. The water influx prevention structure prevents inflow of water into the cooling fan 42 and the substrate on the downstream side thereof by blocking water with the rib B53 and preventing bouncing water from entering by the water influx prevention member 52 even if a good deal of water enters from the suction port 41.
