PURPOSE: To enhance the operational efficiency in taking components in and out by providing a hollow tubular case body with a holding piece projecting from the inner wall of an open end of the case body to hold down the end face of the components stored therein.

CONSTITUTION: A case body 1 is made into a hollow tubular form and is provided at the lower parts of both the side edges with lead receiving part 10 for preventing interference with leads 9. A holding piece 3 is formed integrally with the case body 1 extending in a projecting way from the inner wall of an open end of the case body 1 toward its center to hold down the end face of a component 2 received in the hollow part in order to prevent it from jumping out of the case. Therefore, when the component 2 is taken out of the case body 1, both the side edges of the case body 1 are held and pressed with the fingers to elastically deform the case body 1, so that the interference with the end face of the component 2 of the holding piece 3 is released. As a result, a required number of the components 2 can be taken out and thereafter, when the pressing force is released, the case body returns to the original shape, the holding pieces 3 prevent the remaining components 2 from falling off and the operational efficiency can be improved.
