1. A laser apparatus comprising:
a housing, within which constituent components of a laser that include a resonator and a laser diode which emits laser light toward the resonator are contained;
a temperature adjusting element which is bonded to the housing via an adhesive layer; and
the temperature adjusting element being driven based on a detected temperature of the housing to adjust the temperature of the housing to be a predetermined temperature;
wherein the adhesive layer being that in which a plurality of substantially uniformly shaped spacers that regulate a distance between the housing and the temperature adjusting element are dispersed, the spacers being constituted by one of a glass and a ceramic.
