An electromagnetic valve is constructed such that lengths of sealing portions, formed by a housing 8 and a spool valve 7 respectively between an input port 8a and a feed-back chamber 11 and between the feed-back chamber 11 and a core 4, are unchanged upon movement of the spool valve; and aligning grooves 15a and 15b are respectively formed between the input port 8a and the feed-back chamber 11 and between the feed-back chamber 11 and the core 4, whereby a smooth and stable pressure is constantly obtainable in response to an applied current even though a supplied pressure is high.
