PROBLEM TO BE SOLVED: To provide an electromagnetic pump formed such that width between cores with which a pair of AC electromagnets provided with a vibrator are provided is kept at a constant value and quality is improved. SOLUTION: This electromagnetic pump is coupled to diaphragms 24 and 25 and has a vibrator 43 vibrated axially through carrying current to a pair of AC electromagnets 41. Through vibration operation occasioned with vibration by the vibrator 43, air is sucked in and discharged from pump chambers 29 and 30 one sides of which are partitioned by the diaphragms 24 and 25. A connection part 48 is provided to integrally intercouple coil bobbins 47 with which a pair of the AC electromagnets 41 are provided are arranged in a position deviate from the movement locus of the vibrator 43, and a pair of the AC electromagnets 47 are integrally formed. This constitution keeps a distance between cores 45 (namely, width B between the cores 45) with which the two AC electromagnets 47 are provided at a constant value through the connection part 48 serving as a spacer. |
