The present invention provides a plate-like body connecting method in which functions such that cooling capability is not reduced. There is provided a plate-like body connecting method for connecting at least two plate-like bodies each having passages that extend along at least one of opposite surfaces thereof and between the opposite surfaces, comprising the steps of disposing the plate-like bodies so that edges of the plate-like bodies are abutted with each other; connecting the plate-like bodies along the edges; forming a groove in the one surfaces of the plate-like bodies along the edges; and attaching a closure to and along the groove. Preferably, a distance between the other surfaces of the plate-like bodies and the bottom of the groove is substantially identical to a distance between the other surfaces and the passages, and a distance between the one surfaces of the plate-like bodies and the front end of the projection of the closure is substantially identical to a distance between the one surface and the passages.
