MOUNTING SUBSTRATE AND ELECTRONIC DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a mounting substrate which enables an electronic component to be stably mounted without causing cracks or peeling etc. of a joint member etc. and achieves good heat radiation performance, and to provide an electronic device which uses the mounting substrate.SOLUTION: A mounting substrate includes a base material 11 and a pair of wiring patterns 12 which are disposed on the base material 11 separated from each other. Each wiring pattern 12 includes: a placement part 12a on which an electronic component is mounted; and a hole 12b exposing a part of the base material 11. The hole 12b is placed on an outer edge of the placement part 12a.SELECTED DRAWING: Figure 1
