PROBLEM TO BE SOLVED: To provide an electromagnetic vibration type diaphragm pump extending life of a diaphragm by reducing stress acting on the diaphragm in an irregular direction. SOLUTION: This electromagnetic vibration type diaphragm pump 1 is provided with permanent magnet 5, 6, a pump main body including a moving element 7 reciprocated by magnetic force by electromagnets 2, 3 mutually attracting and repulsing in relation to magnetic force generated by the permanent magnets 5, 6, and diaphragms 8, 9 connected to both end parts of the moving element 7 and provided in compression chambers 14, 15. The moving element 7 of the diaphragm pump sucking and delivering air by reciprocating the moving element 7 corresponding to power source frequency and vibrating the diaphragms 8, 9 is supported by plate springs 24, 25.
