To simply and accurately mount a magnet on a vibrator frame without failure.

This electromagnetic pump is constituted such that s magnet 32 disposed between electromagnets 7 and 7 positioned opposite to each other and vibrated in a direction extending orthogonally to an opposite direction by the magnets 7 and 7 are held in a fitting-in manner in the magnet mounting holes 33a and 34a of the vibrator frame 31, fluid is sucked and discharged through operation of diaphragms 8 and 8 interlocking with the vibrator frame, fluid is sucked and discharged. In this case, the vibrator frame 31 comprises a pair of the vibrator frames 33 and 34 intercoupled in an overlapping state, and lock parts 33b and 34b engaged with end faces 32a and 32b positioned facing the electromagnets 8 and 8 of the magnet 32 are formed integrally with a pair of frames 33 and 34. The magnet 32 is held between the lock parts 33b and 34b of a pair of the frames 33 and 34 in a way to intercouple a pair of frame plates 33 and 34.
