<p>PROBLEM TO BE SOLVED: To prevent electrical components on a substrate from being damaged due to external shocks or still weight exerted to a terminal main body and to avoid spoiling the latitude in design for a terminal case. SOLUTION: This portable mobile terminal is provided with an upper case 2 and a lower case 3 configuring a case main body, a substrate 50 that is placed in the case, a sheet 20 electrically connected via the substrate 50 and a connector 22, and a key button section 10 that has key tops 12 exposed from button holes 4 of the upper case 2 and operated externally. A rigid board 30 is placed between the substrate 50 and the sheet 20 of the key button section 10.</p> |
