Abstract:
1. A high frequency module comprising: a multilayer body including a plurality of insulator layers stacked on each other; a spiral inductor that has an axial direction aligned with a stacking direction of the plurality of insulator layers, and including inductor conductor patterns inside the multilayer body; and a capacitor including capacitor conductor patterns defined by at least one pair of flat-plate conductors provided on different ones of the plurality of insulator layers parallel or substantially parallel to the plurality of insulator layers; wherein at least one of the at least one pair of flat-plate conductors is at a position different from an air core portion of the spiral inductor when looking at the multilayer body from a direction along the stacking direction; the inductor conductor patterns and the capacitor conductor patterns are respectively provided on different ones of the plurality of insulator layers; the at least one pair of flat-plate conductors includes a first flat-plate conductor and a second flat-plate conductor that are opposed to each other in the stacking direction; the first flat-plate conductor is provided on an insulator layer of the plurality of insulator layers which is closer to the inductor conductor patterns than an insulator layer of the plurality of insulator layers on which the second flat-plate conductor is provided; the first flat-plate conductor is at a position different from the air core portion of the spiral inductor when looking at the multilayer body from the direction along the stacking direction; and the second flat-plate conductor is at a position different from the air core portion of the spiral inductor when looking at the multilayer body from the direction along the stacking direction.
