A semiconductor module, comprising a wiring substrate on which wiring is formed,
a semiconductor device electrically connected to the wiring formed on the wiring
substrate, and an external connection terminal arranged on the semiconductor device
mounted side of the wiring substrate so as to be a connected portion between the
wiring and the outside electrically connected thereto, wherein there is formed
an insulating resin layer thicker than the semiconductor device between the wiring
substrate and the external connection terminal.
