The utility model belongs to a silicon nitride ceramic receiving and transmitting coil former. The silicon nitride ceramic receiving and transmitting coil former comprises a coil former body (1) and a positioning groove (6) and is characterized in that a first coil groove (2) and a second coil groove (5) which are identical in dimension are formed in the two ends of the coil former body (1). Two inner winding holes (4) are formed in the coil former body (1). One of the inner winding holes (4) corresponds to a square positioning groove (8). The square positioning groove (8) and a semiround positioning groove (9) are formed in the periphery of the coil former body (1). An included angle alpha between the center line of the semiround positioning groove (9) and one side of the square positioning groove (8) is 60 degrees. The silicon nitride ceramic receiving and transmitting coil former has the advantages of being high in rigidity, good in insulation performance and heat transmission, resistant to high temperatur
