Abstract: The carrier including a plurality of storage sections for individually accommodating electronic parts and a plurality of connecting sections for connecting the adjacent storage sections with each other. Each storage section is provided with a bottom wall and a side wall for defining a recess, and a support section for supporting the electronic part. The support section includes one rib continuously extending on the bottom wall along a generally rectangular profile, and a plurality of columnar projections projecting from the bottom wall to a height generally identical to one another and lower than a height of the rib. The bottom wall includes a first surface extending between the side wall and the rib to define a first region of the recess, and a second surface extending inside the rib to define a second region of the recess shallower than the first region. The columnar projections are arranged in a distributed manner on the second surface of the bottom wall.
