PURPOSE: A self-holding type electronic valve is provided to regulate a stroke of a moving core simply by moving a fixed core and a permanent core integrally, and to restrain the horizontal adsorption of a moving core. CONSTITUTION: A self-holding type electronic valve comprises: a cylindrical bobbin(33) wound with a coil(33a); a fixed core(41) inserted into the bobbin; a moving core(35) installed on the same axle with the fixed core; and at least one permanent magnet(45) adsorbing the moving core to the fixed core for self-holding when sending electric current into the coil, wherein a pair of first and second contact portions(41c) are formed on the fixed core to face each other in the axial direction and connected with each other by a connection having the smaller cross sectional area than the cross sectional area of each contact portion, and at least one permanent magnet is installed between the two contact portions.
