The present invention provides a portable terminal device, such as a portable telephone terminal device including a speaker sound hole in a case side and a main display portion in a case front, in which sound pressure of a terminal front direction can be increased. A sound generated from a speaker 103 accommodated in a case 1 is induced to a terminal side by a speaker sound hole 106. A convex portion 109 is formed in a case portion closer to a rear side than the speaker sound hole 106. The convex portion 109 serves as a sound barrier for preventing a sound ejected from the speaker sound hole 106 from being directed to a terminal rear direction. As a result, sound pressure of a terminal front direction is increased.
