Abstract
To provide an electromagnetic valve where constitution and assembling of a current conduction system to a solenoid portion is simplified to improve assembling easiness and an insulation performance of the current conduction system can easily be secured. In an electromagnetic valve provided with a valve portion having a valve body switching flow paths according to approach to/separation from a valve seat in a housing and a solenoid portion driving the valve body, the housing is formed from electrically insulating synthetic resin, a current conduction terminals constituting a current conduction system of the solenoid portion is inserted into a terminal insertion hole opened on a joining face of the housing with the solenoid portion so that the solenoid portion and the valve portion are fixed to each other, and an opening through which contact terminals extend front the outside to the current conduction terminals in the terminal insertion hole to be electrically connected thereto is provided in the housing.
