PROBLEM TO BE SOLVED: To provide electronic equipment in which a circuit board can be fixed to a case without looseness without using a screw.SOLUTION: Electronic equipment 1 includes: a circuit board 3 mounted with an electronic circuit; a resin lower case 4 having an opening in an upper surface and housing the circuit board 3 in the inside; and an upper case 2 having an opening in a lower surface and attached to the upper surface of the lower case 4. The circuit board 3 has slits 9 opened for fixation. In the lower case 4, grooves 10 for slidingly inserting and housing the edge parts of the circuit board 3 are formed on inner sides of the lower case 4, and projections 12 for fixation each projecting in a pin-shape and each having a barb-shaped locking part 11 at the tip are provided. The locking parts 11 at the tips of the projections 12 for fixation are inserted into the slits 9 from above and locked to an undersurface of the circuit board 3. Thereby, the circuit board 3 is elastically energized upward, and pressed and fixed to upper side inner walls of the grooves 10. |
