PROBLEM TO BE SOLVED: To implement ruggedization of a magnetic cover of an electromagnetic operation part of a two-port solenoid valve and to facilitate closely and securely installing a current-carrying member. SOLUTION: The two-port solenoid valve has a main valve part 1 including a valve member 3 for opening/closing a passage, and the electromagnetic operation part 2 operating the valve member 3. In the electromagnetic operation part 2, an outer shell is formed by the magnetic cover 21. A bobbin 2 around which a coil 23 is wound, a fixed iron core 24 magnetically coupled with the inside of the bobbin, and a movable iron core 25 whose one end is brought into contact with/separated from the fixed iron core 24 and the other end is provided with the valve member 3 are housed in the outer shell. In the magnetic cover 21 having an opening part 21a in a direction orthogonal to a drive direction of a movable iron core 25, an opening 21b through which the movable iron core passes is formed in a wall face on a drive shaft of the movable iron core 25, a seal member 40 to which a current-carrying member is attached is closely installed to the opening part 21a, and the opening 21b is sealed with respect to a current-carrying system of the electromagnetic operation part 2.
