<P>PROBLEM TO BE SOLVED: To solve such a problem that in a circuit module with a metal case where the stray capacitance between the metal case and a mounted electronic component varies when the metal case flexes to cause variation in the circuit module characteristics, and to provide a circuit module in which the circuit module characteristics is less susceptible to variation by increasing the flexure strength of the metal case as much as possible while limiting the number of supports for supporting the metal case and the area on a substrate occupied by the supports as much as possible. <P>SOLUTION: For the circuit module having a rectangular contour, legs of the metal case are arranged at two points on each of long sides facing each other so that a shape formed by connecting respective legs by straight lines becomes square, and its center matches the center of the rectangle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
