Abstract: The disclosed technology relates to ultrasound probes, and the purpose of the technology is to prevent a housing and housing members from cracking and to ensure safety. According to this technology, in an ultrasound probe (12) accommodating one or more elements that include at least a piezoelectric element (3) inside a housing (10), the housing is formed of a plurality of housing members mutually joined. Inside the housing, protrusions having portions extending in a direction other than the direction perpendicular to the joined planes of the housing members are provided, and the housing is filled with a mold member (7) so as to cover the protrusions and the elements accommodated in the housing. The protrusions can be made together with the housing members as units, or can be fixed to the housing members. In another form, the protrusions can be fixed to an element accommodated in the housing.
