Beschreibung
Zusammenfassung:	A magnetic fuel injection valve (100) is provided with a holder (7) made from a magnetic material and provided to the outer peripheral sides of a core (6) and an armature (5), and a housing (8) provided to the outer peripheral side of the holder (7). An electromagnetic passage leading from the housing (8) through the holder (7) to the core (6) has a magnetic path A leading from the holder (7) to the core (6) through the armature (5), a magnetic path B leading directly from the holder (7) to the core (6), and a shared magnetic path C leading to the magnetic path A and the magnetic path B. A magnetic throttling part having a magnetic path cross-sectional area S2 is provided to the holder (7) or the housing (8) constituting the shared magnetic path C. Discrepancies in electromagnetic force among manufactured products are minimized by making S2 be less than the total area S1 of magnetic path cross-sectional areas SA and SB, which are each the minimum cross-sectional area in the magnetic paths A and B, and adjusting the magnetic flux.
