Abstract

To provide a portable blower having excellent battery heat radiating properties. A battery mounting portion projects convexly into an air passage. Outer surfaces of a bottom surface section and side surface sections of the battery mounting portion form part of an inner surface of the air passage. The battery mounting portion holds a battery pack at an attitude that a center of gravity of the battery pack is as close to a handle portion as possible. Specifically, the battery mounting portion holds the battery pack in such a manner that the greatest surface of the battery pack having a substantially cubic shape faces the handle portion. The battery mounting portion holds the battery pack in such a manner that a longitudinal direction of the battery pack faces the air passage.
