1. A dielectric material having a rutile crystalline structure, comprising:
Ti as a major constituent metal element; and
as metal elements other than Ti, a metal element M1 which includes at least one selected from among Ni, Co, and elements belonging to Group 2 according to a periodic table, and a metal element M2 which includes at least one selected from among elements belonging to Group 5 and Group 6 in the periodic table,
on a basis of a total amount of Ti, the metal element M1, and the metal element M2, a molar ratio x of the metal element M1 being in a range of 0.005 to 0.025 and a molar ratio y of the metal element M2 being in a range of 0.010 to 0.050.
