PROBLEM TO BE SOLVED: To provide a thermoacoustic engine capable of being miniaturized and reducing attenuation of acoustic wave. SOLUTION: This thermoacoustic engine includes a first loop pipe 3 provided with a motor 2 for converting heat energy into acoustic energy, a second loop pipe 5 provided with a receiver 4 for converting the acoustic energy into the heat energy, a connection pipe 6 for connecting the first loop pipe 3 and the second loop pipe 5 with each other, and an oscillator 7 disposed in the connection pipe 6 in a state of isolating a working fluid at a first loop 3 side and a working fluid at a second loop pipe 5 side, and oscillatable in the oscillating direction of the working fluids, and the working fluids isolated into two by the oscillator 7, and the oscillator 7 oscillate with a prescribed resonance frequency.
