Abstract
Provided is a surface mount crystal oscillator and a substrate sheet to prevent a decrease in a frequency variable amount by reducing electrostatic capacitance of the crystal oscillator. The surface mount crystal oscillator and the substrate sheet are each configured such that one end of a crystal holding terminal is connected to a corner terminal, and another end of the crystal holding terminal is formed from a center of a short side to be shorter than the one end so as to form an area in which no pattern is formed, and a pattern of a GND terminal is formed on that portion of a rear surface of a substrate which is opposed to the area in which no pattern is formed, so that the pattern (a crystal-mounted pattern) of the crystal holding terminal and the pattern of the GND terminal are not opposed to each other across the substrate.
