Abstract
An electronic circuit board includes a substrate having a multilayer structure including a ground layer, has at least one configuration in which, in a ground layer closest to a signal terminal of an oscillator, a region overlapping a signal terminal in a plan view is a non-forming region of a ground electrode, in a ground layer closest to a first wiring connecting the signal terminal of the oscillator and an input portion of an amplifier, a region overlapping the first wiring in the plan view is a non-forming region of a ground electrode, and in a ground layer closest to a second wiring connecting the signal terminal of the oscillator and an output portion of the amplifier, a region overlapping the second wiring in the plan view is a non-forming region of a ground electrode.
