PURPOSE:To obtain a case for an electronic device which is superior in mass productivity and is easy to assemble, by forming individual case parts integrally through connecting parts and bending them in these connecting parts to assemble the case. CONSTITUTION:A case 1 for small-sized electronic calculator is formed with a synthetic resin, and the upper case part 2 of a keyboard part, the lower case part 3 of the key board part, the lower case part of a display part, and the upper case part 5 of the display part are formed integrally through bendable hinge parts 6, 7, and 8. Hinge parts 6 and 8 are bent to turn the upper case parts 2 and 5 to the positions of lower case parts 3 and 4 as shown by arrows 16 and 17. Claws provided in upper case bodies integrally are fitted firmly to claw engaging parts 20 and 21 provided in lower case parts integrally to join and hold upper case parts to lower case parts, thus assembling the case 1.
