Abstract
A liquid flow path portion of a vapor chamber according to the present invention includes a plurality of main flow grooves which each extend in the first direction and through which working fluid in liquid form passes. A convex array which includes a plurality of liquid flow path convex portions arranged in the first direction via a communicating groove, is provided between a pair of the main flow grooves adjacent to each other. Each of the communicating grooves allows communication between the corresponding pair of the main flow grooves. The width of the communicating groove is larger than the width of the main flow groove.
