A substrate member is a manufacturing component of a module including electronic components mounted on a substrate and sealed with resin. The substrate member has substantially a plate-like shape and is to be the substrate later. A manufacturing process of the modules includes a mounting step of mounting electronic components on a component side of the substrate member, and a sealing step of supplying resin to flow on the component side so that the mounted electronic components are sealed with the resin. The mounting step includes mounting a first electronic component having substantially a flat mounting surface in a first mounting region specified on the component side so that a gap is formed between the mounting surface and the component side. The component side is provided with a first groove for boosting the resin to fill up the gap in the sealing step. Thus, insufficient filling of the resin in the gap between the substrate member and the electronic component is suppressed.

In magnetocardiography, an assisting technique for a doctor diagnosing a heart disease will be provided. In the magnetocardiography, magnetism to be generated from a subject's heart is measured by a magnetic sensor, and from this measured data, a position of center of gravity of excitement wave front in a cardiac muscle excitement propagation process and a transition vector (wave front vector) is calculated by an analyzing computer. With this wave front vector as a feature parameter, the Mahalanobis' distance is calculated from a data base obtained by diagnosing in the past, a possibility (probability) of the subject having a heart disease is presumed on the basis of the Bayes' theorem for displaying. Also, by superimposing on a heart picture, the wave front vector position is displayed, and a cluster classification position in the wave front vector is displayed. Also, by the similar retrieval, another subject extremely similar to the subject in the feature parameter will be retrieved from the data base for screen displaying.
