An ultrasonic flaw detecting apparatus (10) is equipped with an array probe (34), an element group defining part (16), a delay time calculation part (11) and a composite signal generation part (31). The array probe (34) is equipped with multiple piezoelectric elements (33) capable of transmitting and receiving ultrasonic waves to an inspection object (35). The element group defining part (16) defines an element group (13) and calculates a transmission path of ultrasonic beams. The delay time calculation part (11) calculates respective delay time (21) of the piezoelectric elements (33) formingthe element group (13). The composite signal generation part (31) synthesizes detection signals (25) according to delay time (21) and generates composite signals associated with the ultrasonic beams having a transmission path. 在超声波探伤装置(10)中具备：阵列探头(34)，具备能够针对检查对象(35)分别收发超声波的多个压电元件(33)；元件群定义部(16)，定义元件群(13)并运算超声波束的传输路径；延迟时间计算部(11)，计算构成元件群(13)的压电元件(33)的各自的延迟时间(21)；以及合成信号生成部(31)，基于延迟时间(21)将检测信号(25)合成，而生成为与具有传输路径的超声波束有关的合成信号。
