Abstract

An oscillator comprising: an oscillator circuit element having a substrate terminal group and a capacitance section provided on an element substrate, the substrate terminal group comprising at least three substrate terminals including a first substrate terminal and a second substrate terminal, the capacitance section being connected between the first and second substrate terminals; a mount part including an external terminal group comprised of at least one external terminal and mounting thereon the oscillator circuit element; a plurality of inductance lines which are formed among the at least three substrate terminals by conductor wirings which connect between the at least three substrate terminals of the substrate terminal group and the at least one external terminal; and a switch circuit provided on the element substrate to control a connection state of the plurality of inductance lines.
