[Problem] The purpose of the present invention is to provide an electrode member that can be arranged in a suitable arrangement position and used to measure biological information regardless of the size of a subject, and to provide a biological information measurement system and a measurement method using the electrode member.[Solution] An electrode member for measuring biological information has at least a flexible substrate, a single electrode section formed from a flexible conductive material on a first surface of the flexible substrate, a single-pole connector section on the first surface, and a wiring electrically connecting the electrode section and the connector section on the first surface, the electrode member being provided with a member for attaching the electrode member to clothes on a second surface of the flexible substrate. The electrode member is attached at an arbitrary position on an existing garment and used to perform measurement of biological information.
