Device for measuring biological information

A device for measuring biological information by being worn on a measured object, the device comprising:

• a sensor unit configured to measure biological information;
• a device main unit provided with a concavity accommodating the sensor unit in the concavity;
• and
• a holding unit supporting the sensor unit and the device main unit with a space therebetween, the holding unit being elastic,
• the holding unit including an inner periphery part, an outer periphery part with an outer periphery surface, and an inclining part,
• the inner periphery part being coupled to the sensor unit, the inner periphery part having an inner periphery surface, a first surface, and a second surface, the inner periphery surface defining an opening of the holding unit, the first surface and the second surface being opposite to each other such that the inner periphery surface is disposed between the first surface and the second surface, the opening penetrating through the holding unit from the first surface to the second surface, both of the first surface and the second surface contacting the sensor unit
• the outer periphery surface being coupled to the device main unit,
• the inclining part being disposed between the inner periphery part and the outer periphery part,
• a thickness of the inner periphery part and a thickness of the outer periphery part being greater than a thickness of the inclining part,
• the sensor unit being displaced relative to the device main unit by elastic deformation of the holding unit in accordance with an external force applied to the sensor unit.
