PROBLEM TO BE SOLVED: To provide a bulging detection device which can easily and stably detect bulging. SOLUTION: The bulging detection device comprises: a first transmitting antenna arranged so as to face the short sides of a slab drawn in continuous casting and transmitting a first electric wave signal of high frequency toward almost the central part in the thickness direction of the short sides of the slab; a first receiving antenna arranged in the vicinity of the first transmitting antenna and receiving the first reflected electric signal generated in such a manner that the first electric wave signal transmitted by the first transmitting antenna is reflected by almost the central part in the thickness direction of the short sides; and a bulging detecting means connected to the first transmitting antenna and the first receiving antenna, feeding the first electric wave signal to the first transmitting antenna, further receiving the first reflected electric wave signal received by the first receiving antenna, and detecting bulging caused in the short sides of the slab on the basis of variation of a first distance almost to the central part in the thickness direction of the short sides measured using the first electric wave signal and the first reflected electric wave signal.
