An ultrasonic transducer for medical diagnostic examinations which comprises a transducer element having one surface through ultrasonic waves are emitted, an acoustic impedance matcher, and a contact member brought to contact with an object being examined and formed on the one surface of the ultrasonic transducer element. The contact member includes at least a flat plate or an acoustic lens made of a-4-methylpentene-1-base polymer which has high mechanical strength. Transducer arrays and assemblies using such polymer as a member directly contacted with human body are also described.
