Claim Text:
1. An electronic substrate including a tabular base material which installs a heater element and a cooling structure which cools the generated heat of the heater element, in which the base material is possible to be plugged in and out in a case to the direction which is almost parallel to the surface of the base material, the cooling structure provided for the base material is equipped with a first heat radiation part with a hollow shape that radiates the generated heat of the heater element installed in the base material, and a heat transfer part that transfers the generated heat of the heater element to the first heat radiation part, and the first heat radiation part is equipped with a first joint surface that is a face which is almost vertical to the insert and removal direction of the base material, and connects with a second heat radiation part installed thermally in the case through the first joint surface, and a pressing part that presses the first heat radiation part towards the second heat radiation part so that a second joint surface that is a face of which the second heat radiation part is composed and opposes to the first joint surface may connect to the first joint surface thermally, and is installed at a joint part of the heat transfer part and the first heat radiation part, wherein the joint part is a tube installed so as to be extended in the direction which is almost vertical to the first and the second joint surfaces, and the pressing part includes a moving part which is installed so as to move along the tube, a moving part holding part which fixes the moving part in the base material, and an energizing part which energizes the first heat radiation part for the second heat radiation part between the moving part and the first joint surface.
