To provide a solenoid valve having a sensor in which monitor devices for monitoring whether input or output pressure in the solenoid valve is appropriate and a switching state of a valve body are collected to simplify the structure and to facilitate the assembling operation, thereby enhancing safety and reliability.A solenoid valve having a sensor comprises a solenoid valve 1, a base 2 for supplying and discharging pressurized fluid to and from ports P, A, B, EA and EB of the solenoid valve 1, and an intermediate block 3 disposed between the solenoid valve 1 and the base 2. The intermediate block 3 is provided with communication passages 53, 54A, 54B, 55A and 55B for respectively bringing the ports of the solenoid valve and flow paths of the base into communication with each other. A conduit 56 crossing the communication passages is provided in the intermediate block 3. A pressure introducing port 58 opening at the communication passage 53 whose pressure is to be detected is formed in the conduit. A pressure sensor 60 for detecting pressure introduced through the conduit is provided in the intermediate block 3.
