1. An optical device comprising:
- a contact part having a contact surface and an opposing surface, the contact surface adapted to come into contact with a test subject, the opposing surface being opposite the contact surface;
a support body installed on the opposing surface, the support body having a first surface and a second surface, the first surface facing the opposing surface and the second surface being opposite the first surface;
a first element supported by the support body and installed on the second surface; and
a second element disposed between the opposing surface and the support body,one of the first element and the second element being a light-emitting element for emitting light towards a detection site in the test subject,the other of the first element and the second element being a light-receiving element for receiving reflected light, the reflected light being light emitted by the light-emitting element and reflected at the detection site,the first and second elements sandwiching a part of the support body, wherein the part of the support body comprises the first and second surfaces, the first surface directly faces the second element, and the second surface directly contacts the first element,the contact part being formed from a material that is transparent with respect to a wavelength of the light emitted by the light-emitting element.

Abstract
An optical device including a contact part having a contact surface and an opposing surface, the contact surface coming into contact with a test subject and the opposing surface being opposite the contact surface; a support body installed on the opposing surface; a first element supported by the support body; and a second element disposed between the opposing surface and the support body; wherein one of the first element and the second element is a light-emitting element for emitting light towards a detection site of the test subject; another of the first element and the second element is a light-receiving element for receiving reflected light, the reflected light being light emitted by the light-emitting element and reflected at the detection site; and the contact part is formed from a material that is transparent with respect to a wavelength of the light emitted by the light-emitting element.
