摘要： A biological information measurement apparatus capable of improving the SN ratio of a photoplethysmographic signal by reducing stray light in detection light that reaches a light-receiving unit from a light-emitting unit is provided.A biological information measurement apparatus includes a light-emitting unit that irradiates a finger, a light-receiving unit that receives and photoelectrically converts light transmitted through or reflected by the finger and outputs a photoplethysmographic signal, and a processing unit that obtains biological information on the basis of the photoplethysmographic signal. The light-emitting and light-receiving units are disposed, in plan view in a plane perpendicular to the direction of the emitted light or the received light, such that a line passing through the centers of the light-emitting unit and the light-receiving unit is slanted relative to a lengthwise direction of the finger.

摘要： A multilayer substrate includes a laminate, first and second signal lines, first and second ground conductors, and interlayer connection conductors. The first and second signal lines extend along a transmission direction and include parallel extending portions that extend in parallel or substantially in parallel with each other. The first and second ground conductors sandwich the first and second signal lines in a laminating direction. The first and second ground conductors respectively include a first opening and a third opening between the signal lines when viewed from the laminating direction, and respectively include second openings and fourth openings disposed outside in a width direction orthogonal or substantially orthogonal to the transmission direction in the parallel extending portions when viewed from the laminating direction. The interlayer connection conductors are disposed in the transmission direction and at least between the signal lines.
