An array element connecting element (21) of an ultrasonic probe comprises a first-layer main body (210) and a second-layer main body (211), wherein the second-layer main body (211) is bonded to the first-layer main body (210), and an area of the second-layer main body (211) is smaller than an area of the first-layer main body (210). On an area of the first-layer main body (210) that comes out of the second-layer main body (211), at least one first-layer conductive element (2105) that runs through the first-layer main body (210) is arranged. On a lower surface of the second-layer main body (211), at least one second-layer conductive element (2115) that runs through the second-layer main body (211) and the first-layer main body (210) is arranged. The first-layer conductive element (2105) and the second-layer conductive element (2115) connect a signal transmission line (22) to an array element. The connecting element is in a stepped shape. The signal transmission line (22) is connected to an array element component (20) through the array element connecting element (21) in the stepped shape, which thus can provide sufficient space used for connection between the signal transmission line (22) and the array element component (20).La présente invention se rapporte à un élément de raccordement d'élément de réseau (21) d'une sonde ultrasonore, ledit élément de raccordement d'élément de réseau comprenant le corps principal (210) d'une première couche et le corps principal (211) d'une seconde couche, le corps principal (211) de la seconde couche étant relié au corps principal (210) de première couche et une partie du corps principal (211) de la seconde couche étant plus petite qu'une partie du corps principal (210) de la première couche. Sur une partie du corps principal (210) de la première couche qui sort du corps principal (211) de la seconde couche, est agencé au moins un élément conducteur (2105) de la première couche qui traverse le corps principal (210) de la première c
