PROBLEM TO BE SOLVED: To make it possible to produce a pump housing and a plunger using low cost materials while securing operability of the pump in solenoid pump equipment provided with a solenoid with the coil generating electromagnetic force that attracts the movable core to the stationary core side, and a pump having the pump slidably fit into the pump housing. SOLUTION: A coil 32 is provided so as to surround cylindrical stationary core 30 and movable core 31. One end of a connecting tubular portion 33 is connected to a pump housing 8 made of a carbon steel to have its surface cured. The other end is coaxially and integrally connected to the end portion of the stationary core 30 at the opposite side of the movable core 31. One end of a rod 48 made of non-magnetic material to be inserted into the stationary core 30 so as to be movable along the axial direction abuts against the plunger 9 made of carbon steel having its surface cured. The other end of the rod 48 abuts against the movable core 31 coaxially.
