Abstract
A solenoid type electromagnetic valve is configured such that an attraction force arises between an attracting side face of a solenoid core power supply body and an attracted side face of an armature which is facing the attracting side face when a current is conducted through a solenoidal coil, while the attraction force is released between the attracting side face and the attracted side face when the current conducted through the solenoidal coil is cut off, wherein at least one plate member of nonmagnetic material comprising nonmagnetic stainless steel, aluminum alloy or ceramic material is fitted to the attracting side face of the solenoid core power supply body, and fluid insulation resin is filled therein, thereby the fluid insulation resin is solidified and secures the plate member thereto.
