PROBLEM TO BE SOLVED: To provide a plunger solenoid unit which can readily provide an apparatus of optimal specification for an apparatus being applied while taking account of the shape or the attraction force of each compositional member. SOLUTION: The plunger solenoid unit comprises a combination of a plunger unit 12 and a fixed core unit 13 where the plunger unit 12 comprises a first bobbin 2A, a first coil 3A wound around the first bobbin, a first solenoid 4A comprising the first bobbin and the first coil, a first yoke 5A for holding the first solenoid, and a plunger 6 disposed to move freely inward from the end part of the first solenoid, and the fixed core unit 13 comprises second bobbins 2B and 2C, a fixed core 7, a second coil 3B wound around the fixed core, a second solenoid 4B comprising the second bobbin, the fixed core and the second coil, and a second yoke 5B for holding the second solenoid.
