Light-emitting element module, quantum interference apparatus, atomic oscillator, electronic apparatus and moving object

摘要

A light-emitting element module includes a temperature adjustment element, a light-emitting element arranged on a temperature adjustment surface of the temperature adjustment element, a metal layer arranged on the temperature adjustment surface, a relay member arranged on the temperature adjustment surface through the metal layer, a wiring layer arranged on a surface of the relay member at an opposite side to the temperature adjustment surface, a wiring to electrically connect the light-emitting element and the wiring layer, and a wiring to electrically connect a connection electrode and the wiring layer. The wiring layer has an area smaller than an area of a region where the metal layer overlaps the relay member in a plan view.

1. A light-emitting element module comprising:
a temperature adjustment part having a temperature adjustment surface to be temperature-adjusted; a metal layer arranged above the temperature adjustment surface, the metal layer being a rectangle having first through fourth right angle corners in a plan view; a light-emitting element arranged above the temperature adjustment surface through the metal layer, the light-emitting element being located at a center of the metal layer in the plan view; a first relay member arranged above the temperature adjustment surface through the metal layer, the first relay member being located at the first right angle corner of the metal layer in the plan view; a first wiring layer arranged above a surface of the first relay member at an opposite side to the temperature adjustment surface; an element side wiring that is electrically connected between the light-emitting element and the first wiring layer; a first external terminal that is located at an outside of the metal layer in the plan view adjacent to a side between the first and second right angle corners of the metal layer; and a first terminal side wiring that is electrically connected between the first external terminal and the first wiring layer, wherein an area of the first wiring layer is smaller than an area of a region where the metal layer overlaps the first relay member in a plan view, the first relay member is laterally shifted from the light-emitting element in the plan view, and the first external terminal is laterally shifted from the metal layer in the plan view.
