7. A biological information measurement device comprising:
a first member and a second member configured to be attached on a scapha of an auricle in such a way as to clamp the scapha from both sides; and
a measurement means disposed on a portion of the second member, arranged in such a way as not to compress a helix of the auricle when the second member is attached on the scapha of the auricle, and measuring biological information of an artery running in the helix, wherein
the first member and the second member are connected to each other at base end portions of the first member and the second member, wherein the second member includes first and second support member portions that extend perpendicularly from respective end portions of the base end portion of the second member, and are capable of clamping the scapha of the auricle from both sides between tip end portions of the first member and the second member, and
the measurement means includes a light emitting element that is disposed on the first sensor support portion and that radiates light, and a light receiving element that is disposed on the second sensor support portion, wherein the light emitting element and the light receiving element are located at opposite end portions of the base end portion of the second member, in such a way as to face the light emitting element and that receives transmitted light that is radiated from the light emitting element and transmitted through a measurement target site.
