摘要： The present invention provides a transmission medium for ultrasonic diagnosis which comprises a hydrocarbon compound, and/or an ether or ester compound each having a cyclic structure, and has a viscosity of at least 1000 mPa·s at a working temperature. The transmission medium for ultrasonic diagnosis according to the present invention is free from hygroscopicity causing rust generation in a test specimen and worsening the transmission characteristics during use, can impart adhesiveness to a solid within a short period of time, and is particularly excellent in transverse ultrasonic wave transmission, even in a non-contact state in which the test specimen is immersed.
