The ultrasound probe of the disclosed technique is provided with: an ultrasound element unit (2) a tip storage section (7) in which an acoustic medium liquid (6) and the ultrasound element unit (2) are stored in a frame and which is sealed by a holding member a cover member (17a) which is disposed on a surface of the holding member (10a) and an acoustic medium liquid accumulating section (15a) which retains the acoustic medium liquid (6) in a space created by the holding member (10a) and the cover member (17a). The holding member (10a) comprises at least one communication path which is in communication with the acoustic medium liquid accumulating section (15a) and the interior of the tip storage section (7), the cover member comprises at least one ventilation path which is in communication with the acoustic medium liquid accumulating section and the exterior of the tip storage section, and the acoustic medium liquid accumulating section is constituted such that the cross sectional area of the space of the part with which the ventilation path is in communication is larger than the cross sectional area of the space of the part with which the communication path is in communication.Linvention concerne une sonde ultrasonore qui comporte : une unité délément ultrasonore (2) une section de stockage de pointe (7) dans laquelle un liquide de milieu acoustique (6) et lunité délément ultrasonore (2) sont stockés dans un cadre et qui est scellée de manière étanche par un élément de maintien un élément de couvercle (17a) qui est disposé sur une surface de lélément de maintien (10a) et une section daccumulation de liquide de milieu acoustique (15a) qui retient le liquide de milieu acoustique (6) dans un espace créé par lélément de maintien (10a) et lélément de couvercle (17a). Lélément de maintien (10a) comprend au moins un trajet de communication qui est en communication avec la section daccumulation de liquide de milieu acoustique (15a) et lintérieur de la section de stockag
