Summary:PROBLEM TO BE SOLVED: To provide electronic equipment for achieving high antenna performance. SOLUTION: The electronic equipment 1 includes a case 11, an internal conductor member 12 provided in the case 11, a conductor portion 21 which is provided to the case 11 and suppress a leak of unnecessary radiation from the inside to the outside of the case 11, and an antenna 31 which has an antenna element 35 formed on an outside wall surface 15b of the case 11 and uses the conductor portion 21 as an antenna ground 36. The case 11 has a non-conductor portion 56 off the conductor portion 21 at at least a portion of the area where the antenna element 35 is formed. The size of a portion of the antenna element 35 which superposes the non-conductor portion 56 is larger than the size of a portion of the antenna element 35 which superposes the conductor portion 21 when viewed from a direction wherein the antenna element 35 and the case 11 are superposed.
