Embodiment 1
[0041]First, a multilayer polytetrafluoroethylene (PTFE) film having a thickness deviation of 1.3 μm and a surface roughness of 0.65 μm was formed by a casting method.
[0042] Meanwhile, the surface of the plate-like metal substrate 1 was pretreated, and then a polytetrafluoroethylene (PTFE) film was laminated on the pretreated surface of the metal substrate 1 to prepare a laminate.
[0043] Next, the laminated body was cut into a circular shape, and then shaped into a cookware form, and the shaped cookware was subjected to an outer surface treatment to manufacture a cookware main body A.
[0044] Thereafter, the cookware handle B is attached to the cookware body A manufactured as described above to manufacture the figure 1 The cooking utensil (frying pan) shown in .
[0045] The thickness variation, surface roughness, and number of times allowed to fry eggs of the fluororesin film formed on the inner bottom surface of the manufactured cooking utensil (frying pan) were measu...
Embodiment 2
[0048] First, a polytetrafluoroethylene (PTFE) film having a thickness deviation of 4 μm and a surface roughness of 1.6 μm was formed by a dicing method.
[0049] Meanwhile, the surface of the plate-like metal base 1 was pretreated, then cut into a circular shape, and then polytetrafluoroethylene (PTFE) was laminated thereto to prepare a laminate.
[0050] Next, the laminate is formed into a cooker, and the shaped cooker is subjected to an outer surface treatment to manufacture a cooker body A.
[0051] Thereafter, the cookware handle B is attached to the cookware body A manufactured as described above to manufacture the figure 1 The cooking utensil (frying pan) shown in .
[0052] The thickness variation, surface roughness, and number of times allowed to fry eggs of the fluororesin film formed on the inner bottom surface of the manufactured cooking utensil (frying pan) were measured by the following evaluation methods, and the results are listed in Table 1 below.
