Abstract
An ultrasonic wave generation apparatus that includes an ultrasonic wave generation element having an inner space formed by bonding first and second vibrators so as to close off a through-hole or a groove provided in a frame body, and a connecting member that is bonded to the second vibrator supports the ultrasonic wave generation element and is electrically connected to at least one of the first and second vibrators. A ventilation hole that opens into a first side surface of the frame body and that allows the inner space to communicate with the exterior is provided in the frame body. When a direction parallel to the first main surface or the second main surface is a lengthwise direction, an outer side end portion of the ventilation hole in the lengthwise direction and an inner side end portion in the lengthwise direction of the connecting member do not match.
