PROBLEM TO BE SOLVED: To provide a magnetostatic wave element and a magnetostatic wave apparatus which have excellent resonance characteristics.SOLUTION: A magnetostatic wave element 1 comprises: a magnetic film 2 arranged on a principal surface of a support substrate 3; a first bus bar 6 and a second bus bar 7 arranged on the principal surface of the support substrate 3 so as to face each having the entire or partial magnetic film 2 therebetween; a 1-2 connection wire 10 for connecting the first bus bar 6 and the second bus bar 7; a first insulating film 14 for covering the first bus bar 6; a second insulating film 15 for covering the second bus bar 7; a third bus bar 8 arranged on the first insulating film; a fourth bus bar 9 arranged on the second insulating film; and a 3-4 connection wire 11 for connecting the third bus bar 8 and the fourth bus bar 9. Furthermore, the magnetostatic wave element comprises: a 1-4 electrode finger 21 for connecting the first bus bar 6 and the fourth bus bar 9; and a 2-3 electrode finger 22, arranged so as to be adjacent to the 1-4 electrode finger 21, for connecting the second bus bar 7 and the third bus bar 8. |
