Abstract

An electromagnetic valve (1) includes: a solenoid coil (10); a valve body (20) configured to be driven by electromagnetic force of the solenoid coil (10); a coil bobbin (30) including a cylindrical portion (32) and a pair of flanges (34) disposed so as to extend radially outward from opposite ends of the cylindrical portion (32), and holding the solenoid coil (10) in a space formed between the pair of flanges (34) at an outer circumferential side of the cylindrical portion (32); a valve casing (40) including a shaft portion (42) inserted through the cylindrical portion (32) of the coil bobbin (30), and accommodating the coil bobbin (30) disposed around the shaft portion (42), the solenoid coil (10) and the valve body (20); and a filler (2) disposed in a gap, if any, between an inner circumferential surface (33) of the cylindrical portion (32) of the coil bobbin (30) and an outer circumferential surface (43) of the shaft portion (42) of the valve casing (40). The filler (2) has a higher thermal conductivity than air.
